B2B-Commerce-Developer Practice Questions

To check user permissions in Lightning web components, a developer should import two scoped modules: @salesforce/permission and @salesforce/customPermission. The @salesforce/permission module allows the developer to check if the user has access to a standard permission, such as View Setup or Modify All Data. The @salesforce/customPermission module allows the developer to check if the user has access to a custom permission, such as Enable Debug Mode or Manage Orders. The other modules do not exist or are not related to user permissions.

Two things that happen with the cart during tax implementation are that new entries are written to the cart and previous entries are deleted from the cart. A tax implementation 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 implementation can use either an external tax service provider or custom Apex code to perform the tax calculation. When a tax implementation is invoked for a cart, it writes new entries to the cart with a type of Charge and a charge type of Tax. These entries represent the tax amounts and adjustments that are applied to the cart. Before writing new entries to the cart, the tax implementation deletes any existing entries with a type of Charge and a charge type of Tax from the cart. 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. Previous entries are not copied to another object or modified with the new tax calculation, as these are not valid actions for handling existing tax entries.

Three advantages of using ccLog over the Salesforce standard System.debug class are:

• There is no need to use string concatenation to easily tag log statements with a subject. ccLog allows passing a subject parameter to the log method, which will prepend the subject to the log message. For example, ccLog.log('This is a message', 'Subject') will log [Subject] This is a message.
• There is no need to create a User Trace Flag. ccLog can be enabled by setting the value of CO.logToken to true in CCAdmin, which will activate logging for all users who access the storefront.
• There is no need to manually set a cookie to debug with the Site Guest User. ccLog can be enabled for the Site Guest User by appending #ccLog= to the end of the storefront URL in order to get logs in the inspector console. For example, https://my-storefront.com/#ccLog=debug will enable logging for the Site Guest User with the debug level. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Logging
