To be able to efficiently analyze and quickly correct errors in invoicing that lead to early the termination of invoice creation, you can create a clarification case in addition to recording the error message in the application log.

You can create an exception list for messages, by assigning one or more messages (message class and message number) that trigger a clarification case to the invoicing process and optionally to the invoicing type and invoicing category. You can enter a clarification reason for the message in posting area 2673.
