I want to create a credit memo with direct reference to the original billing. Thus the creation of CMR is not required. This is the new feature as of release 4.5a. In SAP system, I've done the configuration for copying control from billing document to billing document, source (F2) target (G2). Copying requirement 027. Pos/neg qty = + and Pricing type = D. I can create a credit memo with reference to a billing now. However, the system allow multiple credit memos. Duplicate credit memo are unwanted in the system.
How to control the system to avoid duplicate credit memo?
Thanks and regards,
