What must a business user do to create a credit memo from a credit memo request?

To create a credit memo from a credit memo request, it is necessary for the business user to follow specific steps that enable the seamless transformation of a request into an actionable credit memo.

First, ensuring that the billing block on the credit memo request is removed is vital. The billing block restricts processing of the request and must be cleared for the system to allow the creation of the credit memo. This step is key to indicating that any issues preventing the processing of the credit memo have been resolved, and it's ready to be executed.

Second, the user must create the credit memo with reference to the credit memo request. This process links the credit memo to its originating request, maintaining necessary data integrity and ensuring the correct amounts and customer details are referenced. This linkage not only simplifies record-keeping but also ensures that the adjustments made via the credit memo correspond appropriately to the initial request.

Both actions are essential to successfully creating the credit memo, thus making "Both A and B" the appropriate choice. It captures the complete process required, emphasizing the importance of addressing any restrictions and properly referencing the original request.
