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.

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 service method that should be overridden in order to allow “without sharing” queries is ccrz.ccService.initSVCDAO. This method is responsible for initializing the service data access object (SVCDAO) that is used by the service class to perform queries. By overriding this method, the user can specify the sharing mode of the SVCDAO, which will determine whether the queries respect or ignore the sharing rules of the current user. For example, ccrz.ccService.initSVCDAO(ccrz.ccAPI.SZ_WITHOUTSHARING) will initialize the SVCDAO with the without sharing mode. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Service Classes, ccService Class

The recommended method for increasing the number of required autocomplete characters that are typed before autocomplete works is to override the autoComplete.search_input.minLength value in the CCRZ.uiProperties file. This file contains various properties that control the behavior and appearance of the user interface components. The autoComplete.search_input.minLength property specifies the minimum number of characters that must be entered before the autocomplete feature is triggered. The default value is 3, but it can be changed to any desired value by overriding it in the CCRZ.uiProperties file. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, UI Properties

In a Lightning Web Component folder, the allowed file extensions include.js-meta.xmlfor the component's metadata,.htmlfor the component's markup, and.jsfor the component's JavaScript class. These files are essential for defining the structure, behavior, and metadata of a LWC. Salesforce LWC documentation provides detailed information on the structure of a LWC bundle and the purpose of each file type within it.

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]

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.

Three actions that are applicable when modifying the number of steps required in the Salesforce Commerce Checkout flow are:

• Perform a template override on the Checkout page. This action will allow you to change the structure and content of the Checkout page, such as adding or removing sections, widgets, or fields. For example, you can override the checkout.handlebars template and modify it according to your requirements.
• Set the value of the configuration setting defined as CO.overrideFlow to TRUE. This setting will enable you to use your own custom checkout flow instead of the default one. You need to set this value to true before you can modify the checkout flow.
• Set the value of the configuration setting defined as CO.useDef to TRUE. This setting will enable you to use a single-page checkout flow instead of a multi-step checkout flow. You need to set this value to true if you want to reduce the number of steps in the checkout flow to one. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Checkout Flow

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

Two ways that a developer should configure taxes in B2B Commerce for Ursa Major are: configure a tax engine using third-party software and configure tax rates and rules for each state in Salesforce B2B Commerce. Configuring a tax engine using third-party software allows the developer to integrate with an external tax service provider that can calculate and apply accurate and up-to-date tax rates and rules for different states and jurisdictions. The developer can use the sfdc_checkout.TaxCalculations interface or the RegisteredExternalService object to connect to the third-party tax service provider’s API or service. Configuring tax rates and rules for each state in Salesforce B2B Commerce allows the developer to implement their own custom tax calculation logic using Apex code. The developer can use custom objects, such as TaxRate__c and TaxRule__c, to store and manage tax rates and rules for different states and products. The developer can also use the sfdc_checkout.TaxCalculations interface to define how to retrieve and apply tax rates and rules for a cart or an order. Using a different pricebook for each state is not a good way to configure taxes in B2B Commerce, as it can create complexity and inconsistency in pricing and discounting logic. Using the Salesforce out-of-the-box tax calculator is not a good way either, as it does not support complex or dynamic tax scenarios that may vary by state or jurisdiction.

The API-based record creation is generally handled in the service-layer responsible for the entity in Salesforce B2B Commerce. The service-layer is a set of classes that provide methods for interacting with the data layer and performing business logic. Each entity, such as product, cart, or order, has a corresponding service class that handles the create, read, update, and delete operations for that entity. For example, ccrz.ccServiceProduct provides methods for creating and retrieving products. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Service Classes

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. Salesforce References: Lightning Web Components Developer Guide: Communicate with Properties, Lightning Web Components Developer Guide: Decorators

When including additional JavaScript files in a Lightning Web Component, it is required that these files are ECMAScript 6 (ES6) modules and have unique names within the component's folder. This ensures proper module resolution and avoids namespace conflicts. Salesforce LWC documentation provides guidelines on organizing component resources, including JavaScript modules, to ensure they are correctly recognized and utilized within the LWC framework.

To expose a public property in a Lightning web component, the developer should decorate the field with the @api decorator. This decorator marks the property as public, which means that it can be set by another component, such as a parent component. The @api decorator also makes the property reactive, which means that any changes to the property value are reflected in the component’s template. The other decorators (@property, @track, and @public) are not valid for exposing public properties in Lightning web components. References: B2B Commerce and D2C Commerce Developer Guide, [Lightning Web Components Developer Guide]

 The correct way to demonstrate the passing of a message from the grandchild component to the grandparent component in LWC is to use the PubSub library. The PubSub library is a utility that enables Lightning web components to communicate across the DOM tree without using intermediaries. The grandchild component can publish a message to a channel, and the grandparent component can subscribe to that channel and receive the message. This way, the communication is decoupled and does not depend on the component hierarchy. Option B shows the correct syntax for using the PubSub library to pass a message from the grandchild component to the grandparent component. Option A is incorrect because it uses the @api decorator to expose a property on the grandchild component, which is not a valid way to communicate with the grandparent component. Option C is incorrect because it uses the @wire decorator to wire a property on the grandchild component to a function on the grandparent component, which is also not a valid way to communicate with the grandparent component. Option D is incorrect because it uses the @track decorator to track a property on the grandchild component, which is not a valid way to communicate with the grandparent component. References: Communicate Across the DOM |Lightning Web Components Developer Guide, Child to grandparent communication in LWC, PubSub Library for Lightning Web Components

To retrieve metadata about a specific picklist, a developer should use the getPicklistValues wire adapter. The getPicklistValues wire adapter imports data from the @salesforce/ui-api module and returns an object that contains information such as the picklist’s label, value, default value, validity, and controlling field values. The getPicklistMetadataValues wire adapter does not exist. The getPicklistMetadata wire adapter does not exist either. The getPicklist wire adapter does not exist either. Salesforce References: [Lightning Web Components Developer Guide: getPicklistValues], [Lightning Web Components Developer Guide: Import User Interface API]

To override inventory in the checkout process, a developer must implement thesfdc_checkout.CartinventoryValidationinterface. This interface provides the necessary methods for custom inventory validation logic, allowing developers to define how inventory checks are conducted during the checkout process. Salesforce documentation on extending and customizing the checkout functionality in B2B Commerce would include guidance on implementing this interface to meet specific inventory validation requirements.

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:

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.

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 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.

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

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

The Salesforce B2B Commerce object that needs to have a record added when defining a new Subscriber Page to be rendered in a CC Page is CC Subscriber Pages. This is a custom object that stores information about the Subscriber Pages, such as the name, description, URL, and Visualforce page. To create a new Subscriber Page, the user needs to create a new record in this object and specify the required fields. The user can then select the Subscriber Page from the CC Page Settings configuration in CCAdmin. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Subscriber Pages

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

The correct syntax for looping through a series of child components which are tiles is option A. Option A uses the for:each directive to iterate over a collection of items and render a template block for each item. The for:each directive requires an expression that evaluates to an array or an iterable object and an item alias that represents the current item in the iteration. The item alias can be used to access the item’s properties or pass them to child components. In option A, the expression is appTiles, which is an array of objects that represent app tiles, and the item alias is appTile, which represents the current app tile object in the iteration. The appTile object’s properties, such as name, description, and icon, are passed to the app-tile child component using attributes. Option B is incorrect because it uses an invalid syntax for the for:each directive. The for:each directive requires a colon (:) after the for keyword, not an equal sign (=). Option C is incorrect because it uses an invalid syntax for the for:each directive. The for:each directive requires an item alias that represents the current item in the iteration, not a key alias that represents the current index in the iteration. Option D is incorrect because it uses an invalid syntax for the template tag. The template tag requires a closing tag (), not a self-closing tag (
