Salesforce Updated B2B-Commerce-Developer Exam Questions and Answers by aahil

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

When implementing code for external pricing comparisons, if the external prices are the same as the sales prices for products in the cart, the implementation should ideally return a status indicating success (such assfdc_checkout.IntegrationStatus.Status.SUCCESS). This indicates that the external pricing verification has passed and there are no discrepancies between the external and sales prices.

 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.
