To create an event listener on a parent component programmatically, the developer should use the following line of code:

this.template.addEventListener(‘notification’, this.handleNotification);

This line of code adds an event listener to the template element of the parent component, which is the root element that contains all the child elements. The event listener listens for an event named ‘notification’, which is a custom event that can be dispatched by any child component. The event listener invokes a method named handleNotification, which is an arrow function defined in the parent component class. The handleNotification method receives the event object as a parameter and can perform any logic based on the event data. The other lines of code are either incorrect or incomplete.

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.

When creating a custom Lightning Web Component (LWC) for use in the Checkout Flow, a developer must set the target in the js-meta.xml file tolwc__FlowComponent. This target specifies that the LWC is intended for use within the flow component framework, allowing it to be utilized specifically in the context of Salesforce Flows, including those used in the checkout process. Salesforce documentation on developing custom LWCs for various targets would detail this requirement, ensuring that developers understand how to correctly package and deploy their components for the intended use case.

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 documentation clarifies the interoperability between Aura and Lightning Web Components (LWCs). An Aura component can indeed contain another Aura component, as well as a LWC, allowing for a mix of component technologies in a single application. However, due to the architectural and design principles of LWCs, a LWC cannot contain an Aura component. This is because LWCs are designed to be lightweight and leverage web standards, which makes them not fully compatible with the older Aura component framework in terms of containment.
