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.

A valid way of referencing the global cc_api_CartExtension apex class via subscriber code is to use ccrz.cc_api_CartExtension. This is the name of the class that is defined in the cloudcraze managed package. The class is global, so it can be accessed by subscriber code. The other options are either invalid or incorrect.

According to the B2B Commerce Developer Guide, the ICart interface provides access to the cart object and its related data. The Details property of the ICart interface returns an ICartDetails object, which contains information about the cart such as the currency, the subtotal, the shipping cost, the tax, and the grand total. The Fields property of the ICartDetails interface returns a map of field names and values for the cart object. Therefore, to get the grand total amount for items in the cart and in the currency of the cart, a developer should use the expression {ICart.Details.Fields.grandTotal}, which returns the value of the grandTotal field from the cart object. References: B2B Commerce Developer Guide, ICart Interface, ICartDetails Interface
