To debug a specific block of Apex code, the Execute Anonymous window in the Salesforce Developer Console or an Integrated Development Environment (IDE) like Visual Studio Code with the Salesforce Extension Pack can be used. This tool allows developers to run Apex code snippets in isolation and observe the results immediately, which is valuable for identifying and resolving defects within specific code blocks.

The equivalent of this code in a Lightning web component is option B. Option B uses the @api decorator to expose firstName as a public property of the Lightning web component and communicate it with other components or services. The @api decorator is a decorator that marks a property or method as public, which means that it can be accessed by other components or services that use or consume this component. The @api decorator also makes the property reactive, which means that it can track changes and update the component accordingly. In option B, firstName is exposed as a public property using the @api decorator and passed to the child element using an attribute. Option A is incorrect because it uses an invalid syntax for exposing firstName as a public property. The @api decorator should be used before the property declaration, not after it. Option C is incorrect because it uses an invalid syntax for exposing firstName as a public property. The @api decorator should be used with parentheses, not without them. Option D is incorrect because it uses an invalid syntax for exposing firstName as a public property. The @api decorator should be used with camel case, not with hyphens.

A valid way of referencing the CC Cart Object whose API name is E_Cart__c in a SOQL query is to use ccrz__E_Cart__c. This is the transformed name of the object that is used by the Salesforce B2B Commerce framework. All custom objects and fields that are part of the cloudcraze managed package have the prefix ccrz__ in their API names. For example, SELECT Id, Name FROM ccrz__E_Cart__c will query the CC Cart Object records. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Query Transformation

A cart item with a type of Charge is created with the Cart Delivery Group Method after the shipping integration. A shipping integration is an integration that calculates and applies shipping costs and options to a cart or an order based on various factors, such as product weight, dimensions, quantity, location, and carrier service level. A shipping integration can use either an external shipping service provider or custom Apex code to perform the shipping calculation. The Cart Delivery Group Method is a method that determines how products are grouped into delivery groups based on their shipping methods and addresses. A delivery group is a logical grouping of products that are shipped together using the same shipping method and address. After performing the shipping calculation for each delivery group, the shipping integration creates a cart item with a type of Charge and a charge type of Shipping for each delivery group. These cart items represent the shipping costs and options that are applied to each delivery group. A cart item with a type of Surcharge, Shipping, or Delivery does not exist or is not related to the shipping integration. Salesforce References: [B2B Commerce Developer Guide: Shipping Integration], [B2B Commerce Developer Guide: Cart Delivery Group Method]

The handlebars helper function that is used on Salesforce B2B Commerce pages and components for formatting price values is formatPrice. This function will format a numeric value as a price according to the currency settings and locale of the storefront. For example, {{formatPrice price}} will format the price value as $1,234.56 for US dollars or €1.234,56 for euros. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Handlebars Helpers

To make an integration available for selection in Salesforce B2B Commerce, a developer must create aRegisteredExternalServicerecord. This can be accomplished using tools like Workbench, which allow for direct interaction with Salesforce's backend database. By registering the external service, the integration becomes selectable within the B2B Commerce setup, allowing it to be associated with specific stores or contexts. Salesforce documentation on integrating external services with B2BCommerce provides step-by-step instructions on registering these services to enable seamless integration and functionality within the platform.

The template that will correctly display the details message only when areDetailsVisible becomes true given the following code in a Lightning Web Component is option C. Option C uses the if:true directive to conditionally render a template block based on the value of areDetailsVisible. If areDetailsVisible is true, the template block inside the <template if:true={areDetailsVisible}> tag will be rendered. Otherwise, it will be skipped. Option A is incorrect because it uses the if:false directive, which does the opposite of if:true. It renders the template block only when areDetailsVisible is false. Option B is incorrect because it uses an invalid syntax for the if directive. The if directive requires a colon (:) after the if keyword, not an equal sign (=). Option D is incorrect because it uses an invalid syntax for the template tag. The template tag requires aclosing tag (</template>), not a self-closing tag (<template/>). Salesforce References: Lightning Web Components Developer Guide: Conditional Rendering, Lightning Web Components Developer Guide: Template Syntax

Two methods from the platformResourceLoader module that are relevant for including third party JavaScript and CSS in a Lightning web component are loadScript and loadStyle. The platformResourceLoader module is a module that provides methods for loading JavaScript or CSS files from static resources or external URLs into a Lightning web component. The loadScript method is used to load a JavaScript file and execute it in the component. The loadStyle method is used to load a CSS file and apply it to the component. The loadClientScript method does not exist or is not relevant for including third party JavaScript in a Lightning web component. The loadCss method does not exist or is not relevant for including third party CSS in a Lightning web component. Salesforce References: Lightning Web Components Developer Guide: Load Scripts and Style Sheets, [Lightning Web Components Developer Guide: platformResourceLoader Module]

To have a customized experience for adding items to the cart and also update the mini cart module, the requirement can be fulfilled by triggering the global “cartChange” event after the Add to Cart Action on the custom button. This event will notify all the components that are listening to it that the cart has changed and they should refresh their data accordingly. The mini cart module is one of these components, so it will update its state based on the new cart data. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Events

 Executing dynamic SOQL inside a without sharing class with a bind variable from PageReference.getParameters(), PageReference.getCookies(), or cc_RemoteActionContext class will open up a major security hole because these sources of input are not sanitized and can be manipulated by malicious users to inject SOQL queries that bypass the sharing rules and access data that they are not supposed to see. For example, a user can modify the URL parameters or cookies to include a SOQL query that returns sensitive data from the database. To prevent this, it is recommended to use static SOQL or escape the bind variables before executing dynamic SOQL.

 To debug a flow and watch all the variables changing as the checkout process is executed, the developer needs to enable two features: show the details of what is executed and render flow in either Lightning Runtime or Lightning Experience. These features are available in the debug options in Flow Builder, and they allow the developer to see real-time details of the flow actions, inputs, outputs, and outcomes in a panel on the right. The developer can also set input variables, restart the flow, and convert the debug run to a test. Option A is incorrect because there is no such thing as a debug tog in Flow Builder. Option C is incorrect because running the latest version of each flow called by subflow elements is not a feature that the developer can enable or disable, but rather a default behavior of Flow Builder. References: Debug a Flow in Flow Builder, B2B Commerce Checkout Flow (Aura), B2B Commerce Checkout Flow Core Actions

To retrieve metadata about a specific object in a Lightning Web Component, a developer can use thegetObjectInfowire adapter. This adapter provides access to the metadata of a specified Salesforce object, including fields, record types, and layouts, which is essential for dynamic component rendering based on the object's schema.

The method that is used to override when extending the Salesforce B2B Commerce logic providers is doLogic. This method is responsible for executing the business logic for each logic provider class, such as validating inputs, performing calculations, applying rules, or updating data. By overriding this method, the user can modify or extend the existing logic or add their own custom logic. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Logic Classes

To handle the subscription lifecycle of a message channel in a Lightning web component, the developer should implement the subscribe() and unsubscribe() methods from the lightning/messageService module. The subscribe() method returns a subscription object that represents the connection to the message channel. The developer can use this object to unsubscribe from the message channel later. The unsubscribe() method takes a subscription object as a parameter and removes the listener from the message channel. The developer should call the unsubscribe() method when the component is disconnected from the DOM, such as in the disconnectedCallback() lifecycle hook, to avoid memory leaks and performance issues.

The other options are not correct because:

• B. stopListener() is not a valid method for handling the subscription lifecycle of a message channel. There is no such method in the lightning/messageService module or the Lightning web component framework.
• C. startListener() is not a valid method for handling the subscription lifecycle of a message channel. There is no such method in the lightning/messageService module or the Lightning web component framework.

References:

• Subscribe and Unsubscribe from a Message Channel
• Lifecycle Hooks
• Use message channel in both direction

• The correct answer is A and C. To use a sophisticated pricing engine hosted as a service outside the org, the developer must make a call to the service and implement the sfdc_checkout.PriceCalculations interface12. The sfdc_checkout.PriceCalculations interface is a standard interface that defines the methods for calculating prices for a cart or an order1. The developer can use this interface to override the default pricing logic and integrate with an external pricing service12. The developer must also make a call to the external service using Apex REST or SOAP callouts3 and handle the response data accordingly.
• Use External Objects and Implement the sfdc_checkout.CartPriceCalculations are not the correct answers. External objects are a way to access data from external data sources in real time, but they are not suitable for integrating with a pricing service that requires dynamic calculations . The sfdc_checkout.CartPriceCalculations interface is a deprecated interface that was used for calculating prices for a cart only1. It has been replaced by the sfdc_checkout.PriceCalculations interface, which supports both carts and orders1. References:

Similar to question 198, when custom code compares external prices with sales prices for cart items and finds them to be the same, the appropriate return value should indicate a successful comparison (such assfdc_checkout.IntegrationStatus.Status.SUCCESS). This signifies that the external prices are aligned with the sales prices, and there are no conflicts.

A theme can be enabled in Salesforce B2B Commerce in three different ways:

• A Storefront setting: The theme can be specified in the Storefront Configuration settings in CCAdmin. This will apply the theme to all users who access the storefront.
• An Account Group field value: The theme can be specified in the Theme field of an Account Group record in Salesforce. This will apply the theme to all users who belong to that account group.
• Dynamically through a hook: The theme can be specified dynamically by extending the cc_hk_theme hook. This hook allows changing the theme based on various factors, such as the user, cart, product, or storefront. For example, the hook can apply a different theme for a specific product category or for a specific user segment.

To implement a custom Terms and Conditions checkbox at checkout in the Aura Commerce template, a developer should add a Desired Delivery Date input field during the checkout flow. The Desired Delivery Date input field allows the customer to enter a date when they want their order to be delivered. The developer can use the @api decorator to expose this field as a public property of the Lightning web component and bind it to the ccCheckoutOrder object. The developer can also use the @wire decorator to get the current cart object and use its properties, such as shipping address and shipping method, to calculate and display an estimated delivery date based on the desired delivery date. The developer can also add validation logic to ensure that the desired delivery date is valid and acceptable. Adding the Expected Delivery Date field to the order confirmation email is not a good solution, as it does not allow the customer to choose or see their delivery date before placing their order. Displaying the Expected Delivery Date on the order page with a Lightning web component is not a good solution either, as it does not allow the customer to enter or change their delivery date after placing their order. Configuring an email alert to the customer when the Expected Delivery Date changes is not a good solution either, as it does not provide a consistent or reliable way of informing the customer about their delivery date.

• The correct answer is A and D. To implement a business rule around shipping, the developer will need to create a class that implements the sfdc_commerce.CartShippingCharges interface and may need to contain logical branching to handle different scenarios12. The sfdc_commerce.CartShippingCharges interface is a standard interface that defines the methods for calculating shipping charges for a cart1. The developer can use this interface to override the default shipping logic and apply custom rules based on the cart amount or other factors12. The developer may also need to use conditional statements or other logic to determine when to use freight shipping or standard shipping3.
• The implementing class cannot call out to another service and a class will need to implement the sfdc_checkout.CartShippingCharges interface are not the correct answers. The implementing class can call out to another service if needed, such as an external shipping service or a pricing engine2. The sfdc_checkout.CartShippingCharges interface is a deprecated interface that was used for calculating shipping charges for a cart only1. It has been replaced by the sfdc_commerce.CartShippingCharges interface, which supports both carts and orders1. References:

In Lightning Web Components (LWC), the root tag for the component's HTML file must be<template>. This tag defines the markup structure for the component and is essential for the LWC framework to correctly render the component in the Salesforce Lightning Experience. The<template>tag is unique to LWC and is not interchangeable with standard HTML tags like<body>,<article>, or<html>. For more information, see the Salesforce LWC documentation:Salesforce LWC HTML Templates Documentation.

 To implement a custom child checkout component for a B2B or B2C store created with an LWR template, the developer must implement the CheckoutStep interface from the commerce/checkout module. This interface defines the methods and properties that the child component must have to communicate with the parent checkout component and the checkout data provider. The CheckoutStep interface extends the UseCheckoutComponent interface, which provides the common functionality for all checkout components, such as loading and saving data, reporting validity, and handling errors.

The other options are not correct because:

• A. CheckoutSavable is not a valid interface for a custom child checkout component. There is no such interface in the commerce/checkout module or the Lightning web component framework.
• B. Checkoutoutinterface is not a valid interface for a custom child checkout component. There is no such interface in the commerce/checkout module or the Lightning web component framework.
• C. CustomCheckout is not a valid interface for a custom child checkout component. There is no such interface in the commerce/checkout module or the Lightning web component framework.

To authorize the org for Command Line Interface (CLI) access so the developer can deploy Lightning web components, the developer should run the command: 'sfdx force:auth:web:login -r “https://login.salesforce.com” and then supply the credentials in the browser when it opens. The sfdx force:auth:web:login command is a Salesforce CLI command that authorizes an org using the web server flow. The web server flow is an OAuth 2.0 authentication flow that opens a browser window and prompts the user to log in to Salesforce and allow access to the CLI. The -r flag specifies the login URL of the org, which is https://login.salesforce.com for production or developer orgs. Running this command will open a browser window and ask the developer to enter their username and password for the org. After successfully logging in, the developer will be able to use the CLI to perform various tasks with the org, such as deploying or retrieving metadata, running tests, or executing commands. Running the command: 'sfdx force:login -r “https://login.salesforce.com” is not a valid way to authorize the org for CLI access, as there is no such command as sfdx force:login. Running the command ‘sfdx force:auth:web:login -a “https://login.salesforce.com”’ is not a valid way either, as the -a flag specifies an alias for the org, not a login URL. Running the command ‘sfdx force:auth:web:login -r “https://login.salesforce.com” -username’me@my-new-org.org"’ is not a valid way either, as there is no such flag as -username. Salesforce References:  Salesforce CLI Command Reference: force:auth:web:login, Salesforce Developer Tools for Visual Studio Code

 A developer needs to make a call to a long running web service which is critical to finalizing their checkout process. The developer should consider the following items in their implementation:

• A new CORS entry may need to be created in Setup. CORS stands for Cross-Origin Resource Sharing, which is a mechanism that allows web browsers to make requests to servers on different domains. If the web service is hosted on a different domain than the B2B Commerce site, the developer may need to add a CORS entry in Setup to allow the browser to access the web service. This entry specifies the origin, path, and method of the request, as well as any headers or cookies that are allowed1.
• A new Named Credential may need to be created in Setup. A Named Credential is a type of metadata that stores the URL and authentication settings of a web service. By using a Named Credential, the developer can avoid hardcoding the web service URL and credentials in their code, and instead reference the Named Credential by name. This makes the code more secure and easier to maintain2.
• An Apex method returning a Continuation will need to be created. A Continuation is a special type of Apex object that allows the developer to make asynchronous calls to long running web services. By using a Continuation, the developer can avoid blocking the main thread and improve the user experience. A Continuation method must return a Continuation object, specify the web service URL and parameters, and register a callback method that handles the response3.

Option D and Option E are incorrect because they are not relevant to the scenario. Option D suggests that the developer should broker the requests to the web service, which means to use an intermediary service that manages the requests and responses. This may be useful for some scenarios, but it is not required for making a call to a long running web service. Option E suggests that the developer shouldcreate a new Remote Site in Setup, which is a way to whitelist the domains that can be accessed from Apex code. However, this is not necessary if the developer uses a Named Credential, which automatically handles the Remote Site setting2. References:

• Set Up CORS
• Named Credentials
• Continuation Class

n: The Commerce Product Data Import resource is the recommended tool for importing products for a B2B or B2C store using a .csv file. This resource supports importing data of related objects, such as ProductCatalog, ProductCategory, Product2, and ProductCategoryProduct, while preserving their relationships. It also does not require additional licenses or third-party tools. The other options are either not specific to Commerce products, or do not support importing data of related objects. References:

• Commerce Product Import Resource
• Import and Export Commerce Data
• B2B and D2C Commerce Data Model

The next step that the developer should do after suspecting that recent edits made to a checkout flow have created a defect and having data points available to use as inputs in reproducing the scenario is to open the flow, select Debug, provide the Input values, and select Run. A flow is a type of application that automates a business process by collecting data and performing actions in Salesforce or an external system. A flow can be used to customize the checkout process in the storefront by defining the steps and logic that are executed when a customer places an order. A flow can be edited or modified using Flow Builder, a point-and-click tool that allows developers to create and manage flows. Flow Builder also provides debugging and testing tools that allow developers to run and troubleshoot flows before deploying them. To debug or test a flow, the developer can open the flow in Flow Builder, select Debug from the toolbar, provide the Input values for the flow variables, and select Run. This will execute the flow in debug mode, which simulates how the flow runs in the org with real data. The developer can use debug mode to verify if the flow works as expected or if there are any errors or issues with the flow logic or actions. Open the flow, select Attach to Live Session, provide the session ID, and select Attach is not a valid next step, asit is not a feature or option available in Flow Builder or Salesforce CLI. Attach to Live Session is a feature that allows developers to attach a debugger to a running Apex session and inspect the state of the code execution. Open the flow, select Debug with Inputs, provide the Input values, and select Run is not a valid next step either, as it is not a feature or option available in Flow Builder or Salesforce CLI. Debug with Inputs is a feature that allows developers to debug an Apex class or trigger with predefined input values and breakpoints. Open the flow, select Debug, provide the session ID for replay, and select Run is not a valid next step either, as it is not a feature or option available in Flow Builder or Salesforce CLI. Replay is a feature that allows developers to replay an Apex log file and inspect the state of the code execution at each line.

Composition is a key pattern in building Lightning Web Components (LWCs). This approach involves creating small, reusable components that can be assembled to form more complex interfaces. This pattern promotes modularity, reusability, and maintainability in the development of web components, aligning with web standards and best practices.

Two technologies that can subscribe to the CommerceDiagnosticEvents event are Aura Components and Lightning web components. CommerceDiagnosticEvents is an event that is fired by Salesforce B2B Commerce when an error occurs in the storefront. CommerceDiagnosticEvents contains information about the error, such as error code, error message, error type, and error details. CommerceDiagnosticEvents can be subscribed by other components or services that want to handle or display the error information in different ways. Aura Components are a type of component that can be used to create custom user interfaces for Salesforce apps. Aura Components can subscribe to CommerceDiagnosticEvents using an aura:handler tag in their markup file. The aura:handler tag specifies an event name, an action attribute that defines a controller function to handle the event, and other optional attributes. Lightning web components are another type of component that can be used to create custom user interfaces for Salesforce apps. Lightning web components can subscribe to CommerceDiagnosticEvents using an @wire decorator in their JavaScript file. The @wire decorator specifies an event name, a function name that defines a handler for the event, and other optional parameters. Processes are not a technology that can subscribe to CommerceDiagnosticEvents, as they are not related to user interface development or event handling. Processes are automated workflows that execute actions based on certain criteria or conditions in Salesforce. Streaming API is not a technology that can subscribe to CommerceDiagnosticEvents either, as it is not related to user interface development or event handling. Streaming API is an API that allows applications to receive notifications of data changes in Salesforce in near real-time. Salesforce References: [B2B Commerce Developer Guide: Handle Errors], [Aura Components Developer Guide: Handle Component Events], [Lightning Web Components Developer Guide: Communicate with Events], [Salesforce Help: Process Automation], [Salesforce Developer Guide: Streaming API]

To reflect the price values stored in an external ERP during the checkout flow, the requirement can be satisfied by overriding the computePricingCart method in ccrz.cc_api_CartExtension and making the callout in this method. This method is responsible for computing the pricing for the cart and its line items. By overriding this method, the user can make a callout to the external ERP and update the pricing information accordingly. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Logic Classes, ccLogicCart Class

After deploying a new Lightning Web Component (LWC) to an org, the typical next step to use the component on a page involves navigating to that page, entering the edit mode (usually through App Builder or a similar interface), and then dragging the new component from the components palette onto the desired location on the page. This process is consistent with Salesforce's modular design approach, allowing for easy integration and configuration of components within the Salesforce ecosystem.

In Salesforce, developers can subscribe to platform events using both Flows and Apex Triggers. This allows for the execution of automated processes in response to the events. Apex Triggers can be written to respond to event messages in the same way they respond to DML events. Similarly, Flows can be configured to trigger upon the receipt of a platform event. This functionality is documented in Salesforce's developer guides and best practices, which emphasize the versatility and power of combining declarative and programmatic approaches to respond to platform events.

Two different types of services that Salesforce B2B Commerce APIs leverage are:

• Logic services which are responsible for implementing business logic associated with entities. These services are defined in the logic classes, such as ccrz.ccLogicCart, ccrz.ccLogicOrder, or ccrz.ccLogicProduct. These classes provide methods for validating inputs, performing calculations, applying rules, or updating data for each entity.
• Data services which are responsible for querying and transforming data from entities. These services are defined in the service classes, such as ccrz.ccServiceCart, ccrz.ccServiceOrder, or ccrz.ccServiceProduct. These classes provide methods for creating, reading, updating, and deleting data for each entity. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Service Classes, Logic Classes

To establish communication between components that are not in the same DOM (Document Object Model) tree, a developer can use the publish-subscribe pattern. The publish-subscribe pattern is a messaging pattern that allows components to communicate with each other without being directly connected or aware of each other. The components can publish events to a common channel and subscribe to events from that channel. The channel acts as a mediator that delivers the events to the subscribers. The developer can use a custom library or a Salesforce platform service, such as Lightning Message Service or Platform Events, to implement the publish-subscribe pattern. Configuring the targets property is not a way to communicate between components that are not in the same DOM tree, as it only defines where a component can be used in an app. Using dispatch events is not a way either, as it only works for components that are in the same DOM tree or have a parent-child relationship. Using @api decorators is not a way either, as it only exposes public properties or methods of a component to other components that use it. Salesforce References: Lightning Web Components Developer Guide: Communicate AcrossSalesforce UI Technologies, Lightning Web Components Developer Guide: Communicate with Events, [Lightning Web Components Developer Guide: Communicate with Properties]

To override pricing during the checkout process in Salesforce B2B Commerce, a developer must implement a class specifically designed for this purpose, such assfdc_checkout.CartPriceCalculations. This class would provide the necessary framework for custom pricing logic to be applied during checkout, ensuring that any custom pricing requirements are met.

To investigate a suspected bug in a checkout flow, comparing previous versions of the flow with the current one can help identify changes that might have introduced the bug. Additionally, Salesforce provides debugging capabilities within the Flow Builder, where a developer can select the debug option, provide input values known to trigger the issue, and execute the flow to observe its behavior, aiding in pinpointing the source of the problem.

Two data types that are considered discrete units of work (code units) within a transaction in the debug logs are web service invocation and Apex class. A discrete unit of work (code unit) is a segment of executable code that runs as part of a transaction in Salesforce. A transaction is a sequence of operations that are treated as a single unit of work and are executed under certain isolation and consistency rules. A transaction can consist of one or more discrete units of work (code units) that are executed sequentially or concurrently depending on various factors such as triggers, asynchronous calls, or limits. A debug log is arecord of database operations, system processes, and errors that occur when executing a transaction or running unit tests in Salesforce. A debug log can capture information about each discrete unit of work (code unit) within a transaction, such as its start time, end time, duration, events, variables, and limits. A web service invocation is a type of discrete unit of work (code unit) that involves calling an external web service from Apex code using SOAP or REST protocols. A web service invocation can be synchronous or asynchronous depending on the method used to make the callout. A web service invocation can be captured in a debug log with its details and results. An Apex class is another type of discrete unit of work (code unit) that involves executing Apex code that defines a class with properties and methods. An Apex class can be invoked from various sources such as triggers, Visualforce pages, Lightning components, or API calls. An Apex class can be captured in a debug log with its details and results. A validation rule is not a type of discrete unit of work (code unit) within a transaction in the debug logs, as it is not a segment of executable code but rather a formula expression that defines a business rule for a field or object. A validation rule can be evaluated during a transaction and cause an error if the rule condition is not met, but it cannot be captured as a separate code unit in a debug log. A Lightning component load is not a type of discrete unit of work (code unit) within a transaction in the debug logs either, as it is not a segment of executable code but rather an event that occurs when a Lightning component is rendered on a web page or application. A Lightning component load can be measured by various performance tools such as Lightning Inspector or Lighthouse, but it cannot be captured as a separate code unit in a debug log.

When a developer configures a tax integration for a store, the previously calculated tax entries during the checkout flow are deleted from the Cart. A tax integration is an integration that calculates and applies tax rates and amounts to a Cart or an Order based on various factors, such as product type, price, quantity, location, and tax rules. A tax integration can use either an external tax service provider or custom Apex code to perform the tax calculation. When a developer configures a tax integration for a store, any existing tax entries in the Cart are deleted before calling the tax integration service or method. This ensures that the tax calculation is accurate and up-to-date based on the current state of the Cart and avoids any conflicts or inconsistencies with previous tax entries. The previously calculated tax entries are not ignored during recalculation, saved prior to recalculation, or modified with the new tax calculation, as these are not valid actions for handling existing tax entries. Salesforce References: B2B Commerce Developer Guide: Tax Integration, B2B Commerce Developer Guide: Tax Calculation Flow

In the context of Salesforce debug logs, code units represent discrete units of work within a transaction. Apex classes (B), Web service invocations (C), and Workflow invocations (E) are considered code units as they encapsulate specific operations or sets of logic that can be executed as part of a transaction. Validation rules (A) and the loading of Lightning components (D) are not considered discrete units of work in the same way, as they are part of the declarative interface and front-end framework, respectively. For more details on how Salesforce handles transactions and debug logs, refer to the Salesforce Developer Documentation:Salesforce Developer Documentation on Transactions and Debug Logs.

The product will not appear on the Portal and therefore cannot be added to the cart. A product is assigned to the entitlement policy but is missing from the Price Book related to the Buyer Group. The entitlement policy has View products and View prices in catalog checked. An entitlement policy is a set of rules that determines which products and prices a buyer group can access in the storefront. A buyer group is a group of buyers that share the same business relationship with the seller. A price book is a collection of prices for products that are available for purchase in the storefront. A product is a record that represents an item that can be sold in the storefront. To make a product visible and purchasable in the storefront, it must be assigned to both an entitlement policy and a price book that are related to the buyer group. If a product is assigned to an entitlement policy but not to a price book, it will not appear on the Portal and therefore cannot be added to the cart, regardless of the entitlement policy settings. The product will appear on the Portal with Price Unavailable status and can also be added to the cart is not a correct answer, as it contradicts the behavior of a product that is not in a price book. The product will appear on the Portal with Price Unavailable status but cannot be added to the cart is not a correct answer either, as it also contradicts the behavior of a product that is not in a price book. The product will not appear on the Portal but can be searched since it is part of the entitlement policy is not a correct answer either, as it also contradicts the behavior of a product that is not in a price book.

 To make an integration available for selection, a developer must create a RegisteredExternalService record using Workbench and create an Apex class that uses the integration framework. Creating a RegisteredExternalService record using Workbench allows the developer to register their custom integration class as an external service in Salesforce B2B Commerce. The RegisteredExternalService record contains information such as the class name, version, display name, description, and category of the integration class. The category determines where and how the integration class can be used in B2B Commerce, such as ShippingService or TaxService. Creating an Apex class that uses the integration framework allows the developer to define custom logic for integrating with an external service provider’s API or service. The integration framework provides interfaces and classes for various types of integrations, such as shipping, tax, payment, inventory, and freight. The developer can implement these interfaces and classes in their custom Apex class and override their methods with their own logic. Modifying the StoreIntegratedService to map to an Apex class ID using Workbench is not a required step for making an integration available for selection, as it is only used for registering internal services that are provided by Salesforce B2B Commerce out-of-the-box. Entering the integration class name and version in store administration is not a required step either, as it is only used for selecting an existing integration class that has already been registered as an external service. Salesforce References: [B2B Commerce Developer Guide: Integration Framework], [B2B Commerce Developer Guide: RegisteredExternalService Object]

A Lightning Web Component can contain an Aura component, and an Aura component can contain a Lightning Web Component. This interoperability allows for a smoother transition from Aura to LWC and enables developers to utilize the strengths of both frameworks. However, nesting a Lightning Web Component within an Aura component which in turn contains a Lightning Web Component (Option C) is not a standard practice. For more information, refer to the Salesforce documentation on using Aura and Lightning Web Components together:Salesforce Aura and LWC Interoperability Documentation.

Three statements that are true about Global API versioning are:

• Calling in with an API version set to lower than 1 will result in an exceptional case where the exception class ccrz.BelowMinAPIVersionException will be returned to callers. This exception indicates that the API version is not supported by the framework and the caller should use a higher API version.
• The API version is scoped at the Class API level and NOT at the method level. This means that all the methods in a class will use the same API version that is specified by the caller. For example, if the caller passes an API version of 4 to ccrz.ccServiceProduct.getProducts(), then all the other methods in ccrz.ccServiceProduct will also use API version 4.
• Calling in with an API version set to more than current maximum will result in exception case where the exception class ccrz.ExceedsMaxAPIVersionException will be returned to callers. This exception indicates that the API version is not supported by the framework and the caller should use a lower API version. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, API Versioning

To ensure that a custom field is available to display on a given page, the Developer needs to override the Service Class that the page uses and update the Service Management in CCAdmin for the given storefront to use this new Service Class. The Service Class is responsible for retrieving and setting data for a given page. The Logic Class is responsible for implementing business logic and validation rules for a given page. Creating a new Service Class or Logic Class is not necessary, as overriding an existing one can achieve the same result. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Service Classes, Logic Classes

The sizing keys used in the Salesforce B2B Commerce Global APIs perform five distinct operations. Three of these operations are:

• Refetch data (used on some Logic classes): This operation indicates that the data should be refetched from the database instead of using the cached data. For example, ccrz.ccServiceCart.getCart(ccrz.ccAPI.SZ_REFETCH) will refetch the cart data and refresh the cache.
• Related Query to call (sub queries or direct queries): This operation indicates that the related entities should be retrieved by using sub queries or direct queries. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SUBQUERY) will use sub queries to fetch the related entities for each product, while ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_DIRECTQUERY) will use direct queries to fetch the related entities separately.
• Object type casting: This operation indicates that the data should be cast to a specific object type. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SOBJECT) will cast the data to sObjects instead of transformed objects. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Data Sizing Conventions

Two statements that are accurate about the Cart Item with a Type of Charge are that it is linked directly to a Cart Id and that it is linked directly to a Catalog Id. A Cart Item with a Type of Charge is a special type of Cart Item that represents an additional charge or fee that is applied to a Cart, such as shipping, handling, or tax. A Cart Item with a Type of Charge is linked directly to a Cart Id, which means that it belongs to a specific Cart and can be retrieved or updated along with other Cart Items. A Cart Item with a Type of Charge is also linked directly to a Catalog Id, which means that it references a specific Catalog that contains the products and prices for the store. A Cart Item with a Type of Charge is not created with the Cart Delivery Group Method after the shipping integration or after the freight integration, as these are not related to the creation of Cart Items. The Cart Delivery Group Method is a method that determines how products are grouped into delivery groups based on their shipping methods and addresses. The shipping integration and the freight integration are integrations that calculate and apply shipping costs and freight charges to a Cart or an Order.

The format that the custom Salesforce relationship with the API name, My_Relationship_Name__r.My_Name__c is queried and transformed into by default in Salesforce B2B Commerce is myRelationshipName.myName: value. This is done to follow the JavaScript naming convention and to avoid conflicts with the standard Salesforce fields and relationships. The transformation rules are as follows:

• Remove any namespace prefix from the field name, such as ccrz__ or cloudcraze__.
• Remove any underscores from the field name and capitalize the first letter of each word after an underscore, such as MyRelationshipName and MyName.
• Lowercase the first letter of the field name, such as myRelationshipName and myName.
• Use a dot (.) to separate the relationship name and the field name, such as myRelationshipName.myName.
• Use a colon (:) to separate the field name and the field value, such as myRelationshipName.myName: value. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Query Transformation

To help troubleshoot and respond to actions in checkout, the developer’s code should listen for CommerceDiagnosticEvents. CommerceDiagnosticEvents is an event that is fired by Salesforce B2B Commerce when an error occurs in the storefront. CommerceDiagnosticEvents contains information about the error, such as error code, error message, error type, and error details. CommerceDiagnosticEvents can be subscribed by other components or services that want to handle or display the error information in different ways. The developer’s code can listen for CommerceDiagnosticEvents using an aura:handler tag in Aura Components or an @wire decorator in Lightning web components. The developer’s code can also use the event information to perform custom logic or actions based on the error, such as logging, reporting, or notifying. CommerceBubbleEvents is not an event that the developer’s code should listen for in checkout, as it is not related to troubleshooting or responding to actions. CommerceBubbleEvents is an event that is fired by Salesforce B2B Commerce when a user interacts with a bubble component in the storefront. A bubble component is a user interface element that displays information or options in a pop-up window when clicked or hovered over. CommerceBubbleEvents contains information about the user interaction, such as bubble name, bubble type, and bubble value. CommerceErrorEvents is not an event that the developer’s code should listen for in checkout either, as it is not related to troubleshooting or responding to actions. CommerceErrorEvents is an event that is fired by Salesforce B2B Commerce when a validation error occurs in the storefront. CommerceErrorEvents contains information about the validation error, such as field name, field label, and error message. CommerceActionEvents is not an event that the developer’s code should listen for in checkout either, as it is not related to troubleshooting or responding to actions. CommerceActionEvents is an event that is fired by Salesforce B2B Commerce when a user performs an action in the storefront. CommerceActionEvents contains information about the user action, such as action name, action type, and action parameters. Salesforce References: B2B Commerce Developer Guide: Handle Errors, B2B Commerce Developer Guide: Handle User Interactions with Bubble Components, B2B Commerce Developer Guide: Handle Validation Errors, B2B Commerce Developer Guide: Handle User Actions

The REST APIs in Salesforce B2B Commerce support pass-through parameter handling by passing parameters through the service handlers. This means that any parameters that are not recognized by the REST API framework will be passed to the service handler class that implements the API logic. The service handler class can then use these parameters for custom logic or validation.

You should avoid using ccLog in two scenarios. First, you should avoid using ccLog with System.LoggingLevel.ERROR when passing in a method invocation as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.ERROR, ‘D:something’, myCallToGetMessage(pl) ). This is because if an exception occurs within the method invocation, it will not be caught by ccLog and will cause an unhandled exception on the page. Instead, you should use a try-catch block around the method invocation and log the exception separately. Second, you should avoid using ccLog with System.LoggingLevel.DEBUG when passing in a large collection or object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrderList’, myOrderList), where myOrderList is a list of orders. This is because logging large objects can cause performance issues and consume a lot of heap space. Instead, you should use a loop to log only the relevant fields or properties of the object or collection. You can use ccLog with System.LoggingLevel.WARN when passing in a string as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.WARN, ‘D:something’, ‘Something unexpected occurred: The data we were expecting for pl was not there,’). This is a valid use case for logging a warning message. You can also use ccLog with System.LoggingLevel.DEBUG when passing in a small object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrder’, myOrder), where myOrder is an order object. This is acceptable as long as the object is not too large or complex. Salesforce References: [B2B Commerce Developer Guide: Logging]

Two guidelines for logging that are used within the core Salesforce B2B Commerce product are:

• The close method of ccrz.ccLog must be called at the end of the remote action. This method will flush the log messages to the browser console or to a custom object, depending on the logging mode. If this method is not called, the log messages may not be displayed or saved properly.
• No calls to ccrz.ccLog can be made before cc_CallContext.initRemoteContext is executed. This method will initialize the call context object, which contains information such as the current user, cart, storefront, and configuration settings. These information are required for logging, so calling ccrz.ccLog before initializing the call context will result in an error. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Logging

Three actions that a developer must take, in a B2B Commerce store, to accept credit card payments using a client’s chosen payment provider are: create a named credential for authentication with the payment provider, create an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface, and create a PaymentProviderGateway record for the custom payment provider class. Creating a named credential for authentication with the payment provider allows the developer to securely store and manage authentication information, such as username, password, token, or certificate, for connecting to the payment provider’s API or service. Creating an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface allows the developer to define custom logic for processing credit card payments using the payment provider’s API or service. The interface provides methods for validating credit card information, authorizing payments, capturing payments, voiding payments, and refunding payments. Creating a PaymentProviderGateway record for the custom payment provider class allows the developer to register the custom payment provider class as a payment gateway in the store and associate it with a payment method. Creating a RegisteredExternalService record for the custom payment provider class is not a required action, as this is only used for registering external services that are not related to payment processing, such as tax or shipping services. Creating an Apex class that implements the commercepayments.PaymentGatewayAdapter interface is not a required action either, as this is only used for D2C Commerce stores, not B2B Commerce stores. Salesforce References: B2B Commerce Developer Guide: Payment Integration, B2B Commerce Developer Guide: Payment Gateway Adapter Interface, B2B Commerce Developer Guide: Payment Provider Gateway Object

Data for Lightning web components should be provided as independent properties that take simpler, primitive values (e.g. String, Number, Boolean, Array). Providing data as independent properties allows the developer to expose data as public or private properties of the Lightning web component and communicate data between components or services. Providing data as simpler, primitive values allows the developer to use data types that are supported by JavaScript and Lightning web components and avoid unnecessary or complex conversions or transformations. Providing data as a few properties that contain sets (objects) of data is not a good way to provide data for Lightning web components, as it can create confusion or inconsistency in data structure and access. Providing data as one property that contains all data in one set (object) is not a good way either, as it can create complexity or inefficiency in data management and manipulation. Providing data as a single property object that contains sets (objects) of data is not a good way either, as it can create redundancy or duplication in data storage and retrieval. Salesforce References: Lightning Web Components Developer Guide: Communicate with Properties, Lightning Web Components Developer Guide: Data Types

To introduce new screen behavior in a checkout flow step, a developer should clone the appropriate subflow and replace the Lightning web components in it. A subflow is a reusable flow that can be invoked from another flow as an element. A checkout flow is a flow that defines the steps and components for the checkout process in the storefront. A checkout flow consists of several subflows, each of which corresponds to a checkout step, such as Cart, Shipping Address, Payment, or Order Summary. To introduce new screen behavior in a checkout flow step, a developer should clone the subflow that matches the checkout step they want to modify and replace the Lightning web components in the cloned subflow with their custom components. The developer can then update the checkoutSteps.xml file to point to the cloned subflow instead of the original subflow. Modifying the property mappings in checkoutSteps.xml is not a valid way to introduce new screen behavior in a checkout flow step, as it only affects how data is passed between subflows, not how screens are displayed or rendered. Editing the default subflow directly is not a valid way either, as it can cause conflicts or errors with other stores or environments that use the same default subflow. Adjusting next-state in previous subflow configuration is not a valid way either, as it only affects how subflows are transitioned or navigated, not how screens are displayed or rendered.

The difference between Gross Layout Overrides and Subscriber Templates is that Subscriber Templates allow for modification of the header and the footer, while Gross Layout Overrides allow for modification everything inside the header and footer. Subscriber Templates are custom Visualforce pages that can replace the standard header and footer components on a page. Gross Layout Overrides are custom Visualforce pages that can replace the default layout of a page, such as the number of columns, theposition of widgets, or the content of sections. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Subscriber Templates, Gross Layout Overrides

In a Lightning Web Component's HTML file, using<article>,<body>, or<html>as the first (root) element would produce an error because the LWC framework requires<template>as the root tag. The<template>tag is necessary for defining the component's structure and supports the framework's reactive and rendering capabilities. The use of other HTML tags as the root element is not supported and will result in an error during component compilation or runtime. Refer to the Salesforce LWC documentation for proper component structure:Salesforce LWC Component Structure Documentation.

In Lightning Web Components, the decorators@api,@track, and@wireplay crucial roles. The@apidecorator is used to expose public properties and methods, making them accessible to other components. The@trackdecorator is used to mark private properties as reactive, so the UI updates when their values change. The@wiredecorator is used to wire Apex methods or Salesforce data to the component. Salesforce documentation on LWC development extensively covers these decorators, explaining their usage and best practices.

To retrieve metadata about a specific object, a developer should use the getObjectInfo wire adapter. The getObjectInfo wire adapter imports data from the @salesforce/schema module and returns an object that contains information such as the object’s label, key prefix, fields, child relationships, record type infos, and theme. The getObjectMetadata wire adapter does not exist. The getObject wire adapter does not retrieve metadata, but rather returns a record object based on the record ID. The getObjectDescribe wire adapter does not exist either. Salesforce References: [Lightning Web Components Developer Guide: getObjectInfo], [Lightning Web Components Developer Guide: Import Salesforce Schema]

Custom labels are text values that can be translated into any language that Salesforce supports. They are useful for displaying language-specific text in Lightning web components. To use custom labels in a LWC, the developer needs to create them in the Setup menu and assign them to a language and a value. Then, the developer can import them in the LWC using the @salesforce/label scoped module. For example, if the developer has a custom label named welcomeHeader, they can import it as follows:

import welcomeHeader from '@salesforce/label/c.welcomeHeader';

Then, they can use it in the HTML template or the JavaScript file of the LWC. For example, in the HTML template, they can use it as follows:

HTMLAI-generated code. Review and use carefully. More info on FAQ.

<template>

<h1>{welcomeHeader}</h1>

</template>

The custom label will automatically display the translated value based on the user’s language preference. The developer can also use the lightning-formatted-text component to format the custom label value with HTML tags.

The other options are not correct because:

• A. Importing static resources for the text values is not a recommended way to translate text values in a LWC. Static resources are files that are stored in Salesforce and can be referenced by applications. They are not designed for storing language-specific text values and they do not support automatic translation based on the user’s language preference.
• B. Using a CustomLabel xml file in the LWC to add the text values there is not a valid option. Custom labels are not stored in xml files, but in the Setup menu. They cannot be added directly to the LWC, but they need to be imported using the @salesforce/label scoped module.
• D. Creating a custom Metadata object for the text values and querying it in the LWC is not a feasible option. Custom Metadata objects are records that store configuration data that can be deployed and packaged. They are not intended for storing language-specific text values and they do not support automatic translation based on the user’s language preference. Querying them in the LWC would also require an Apex class and a wire service, which would add unnecessary complexity to the solution.

To bring picklist values into a Lightning Web Component (LWC), a developer needs to import specific modules from thelwcandlightning/uiObjectInfoApinamespaces. ThegetPicklistValuesfunction from thelightning/uiObjectInfoApimodule is used to fetch the picklist values based on record type and field metadata. Additionally, importing{ LightningElement, wire }fromlwcis essential for defining the LWC class and using the@wiredecorator to wire thegetPicklistValuesto a property orfunction. Salesforce documentation on LWC and utilizing theuiObjectInfoApiprovides clear guidelines on how to implement this functionality.

The conversion flag that allows for sObjects to be returned from the Global API’s when provided as a Boolean parameter with a value of true is ccrz.ccAPI.SZ_SOBJECT. This flag indicates that the API should return the raw sObjects instead of the transformed objects that are usually returned by the API. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SOBJECT,true) will return the Product2 sObjects instead of the ccrz__E_Product__c objects. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Data Sizing Conventions

A valid way of referencing the global cc_api_CartExtension apex class via subscriber code is to use ccrz.cc_api_CartExtension. This is the name of the class that is defined in the cloudcraze managed package. The class is global, so it can be accessed by subscriber code. The other options are either invalid or incorrect. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, API Classes

The handlebars helper expression that is used in Salesforce B2B Commerce pages and components to toggle the display of a block of markup is {{#ifConfig ‘Field__c’}} … {{/ifConfig}}. This expression will evaluate the value of the configuration setting with the API name Field__c and render the block of markup if the value is true, or skip it if the value is false. For example, {{#ifConfig 'CO.showMiniCart'}}

To make an API call in a Lightning web component (LWC), a developer should use the connectedCallback lifecycle hook. The connectedCallback lifecycle hook is invoked when the component is inserted into the DOM. This is the ideal time to make an API call, as the component is ready to receive and display data. Thedeveloper can use the fetch API or a third-party library, such as axios, to make the API call and handle the response. The renderedCallback lifecycle hook is not a good choice for making an API call, as it is invoked every time the component is rendered or rerendered. This can cause unnecessary or repeated API calls and affect performance. The errorCallback lifecycle hook is not a good choice either, as it is invoked when an error occurs in the component or in one of its children. This is not related to making an API call, but rather to handling errors. The disconnectedCallback lifecycle hook is not a good choice either, as it is invoked when the component is removed from the DOM. This is not a suitable time to make an API call, as the component is no longer visible or active. Salesforce References: Lightning Web Components Developer Guide: Lifecycle Hooks, Lightning Web Components Developer Guide: Call an Apex Method Imperatively

Two kinds of queries that the methods in Salesforce B2B Commerce services perform by default are SOQL and schema-less queries. SOQL is the query language that is used to retrieve data from Salesforce objects and fields. Schema-less queries are queries that do not specify the object or field names explicitly, but use placeholders instead. For example, ccrz.ccServiceDao.getQuery('SELECT Id FROM Account WHERE Name = :name') is a schema-less query that uses :name as a placeholder for the field name. The framework will transform this query to use the actual field name based on the query transformation rules. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Query Transformation
