We have one validation in GGB0 ( cost accounting) for the combo of G/L, cost center and t code for credit and debit memo, and we are creating credit and debit memo with reference to credit memo request and debit memo request. That validation only triggers when billing document is released to accounting.
Now business wants that this information ( missing about cost center, WBS) should trigger earlier before creation of credit/debit memo ( means at the level of sales order and or credit/debit memo request).
So may I define validation this validation in SD ? or do I need to include the document type ( for credit/debit memo request) in GGB0?
How can I achieve this?
