What is appended to the subquery name as part of its transformation by default in Salesforce B2B Commerce?
A . A subscriber-supplied token
B . "__ccrz"
C . The "*" symbol
D . The letter "S"

Answer: B

Explanation:

A query containing a subquery is executed. By default, in Salesforce B2B Commerce, “__ccrz” is appended to the subquery name as part of its transformation. This is done to avoid conflicts with the standard Salesforce fields and relationships. For example, SELECT Id, Name, (SELECT Id, Name FROM Contacts) FROM Account will be transformed to SELECT Id, Name, (SELECT Id, Name FROM Contacts__ccrz) FROM Account__ccrz.
