3779266 - Credit memo assignment does not copy the original invoice assignment

• A credit memo references an invoice, but the Assignment field in Manage Customer Line Items app contains the credit memo number(or another value) instead of the original invoice assignment.
• The behavior occurs although the credit memo was created with reference to the invoice.

SAP S/4HANA Cloud Public Edition

• During posting of the credit memo accounting document, the system attempts to read the open item of the referenced invoice.
• If the accounting document of the referenced invoice has not yet been created, the system cannot retrieve the Assignment from the original invoice.

Example:

Document    Journal Entry Creation Time
Credit Memo    18.11.2024 03:39:23
Invoice    18.11.2024 03:40:47

In this example, the accounting document for the credit memo is created before the accounting document for the invoice.

Since the invoice open item does not yet exist:

• No Assignment can be copied from the invoice.
• The system falls back to the standard Assignment determination logic.
• Typically, the Assignment provided by SD Billing is used.

This behavior is expected.

• Verify the posting timestamps of the accounting documents.
• If the credit memo accounting document was created before the invoice accounting document, the Assignment cannot be copied because the referenced accounting document was not yet available during posting.
• No correction is required, as this is standard system behavior.
• To avoid this situation, ensure that the accounting document for the original invoice is created before the accounting document for the credit memo whenever possible.

Note:
The Assignment field is determined during accounting document creation and is not recalculated after the referenced invoice is posted.
