Pearson B2B-Commerce-Developer New Attempt

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.

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.

To fire a custom event called CustomEvent from the Lightning web component and propagate it up to the DOM, the developer must set two event settings: bubbles and composed. The bubbles setting determines whether the event bubbles up through the component’s ancestors in the DOM tree. The composed setting determines whether the event crosses the shadow boundary and reaches the light DOM. Setting both bubbles and composed to true allows the event to be handled by any element in the DOM that listens for it. The cancelable setting is not required for firing or propagating the event, as it only determines whether the event can be canceled by calling preventDefault() on it. Setting composed to false would prevent the event from reaching the light DOM and limit its propagation to the shadow DOM.

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
