SAP Note 17410 - Posting credit memos; payments and dunning

Symptom:

Payment terms for credit memos not functioning as expected:

1. When credit memos are posted, the payment terms are not taken from the customer or vendor master record as is the case with invoices.

2. During dunning or payment runs, the system does not take the payment terms entered in the credit memo into account.

Cause and prerequisites

Works as designed.

1. Credit memos are either referenced to an invoice or not. A credit memo with an invoice reference (field BSEG-REBZG) has exactly the same payment terms as the invoice.

2. A credit memo without an invoice reference is always due on the baseline date (the exceptions to this are credit memos which have an explicitly-stated value date).
Credit memos of this type have the indicator "V" in addition to the specified payment method in field BSEG-RFBZG (see online documentation for this field).

Solution
Credit memos that have a reference to an invoice should be posted using this reference (when processing in the background, you must fill field BSEG-REBZG accordingly).
Credit memos that refer to an inoice or have had other terms explicitly specified for them should be posted as credit memos with a fixed value date (with batch input processing, put a "V" next to the payment term in field BSEG-REBZG).
