3800126 - Intercompany Rebilling: Supplier Invoice Does Not Derive Receiver Cost Center From Allocation And Falls Back To Default (SAP S/4HANA Cloud Public Edition)

• In intercompany rebilling, the supplier invoice generated via IDoc does not automatically derive the receiver cost center as the cost object and instead uses a default from Manage default account assignment.
• The customer invoice posts correctly with the profit center derived from the sender cost center, but the analogous derivation for the receiver cost center on the supplier invoice does not occur.
• Expected behavior: the supplier invoice should inherit/derive the specific receiver cost center used in the allocation, similar to profit center derivation on the customer invoice.
• No error message is displayed.

1. Create an intercompany sales order.
2. Run an intercompany allocation using a sender cost center in the sending company and a receiver cost center in the receiving company.
3. Create the intercompany billing request.
4. Create the intercompany invoice.
5. Observe the customer invoice journal entry in the sending company where the profit center is derived from the sender cost center.
6. Observe the supplier invoice journal entry in the receiving company posted with a cost center taken from Manage default account assignment instead of deriving the receiver cost center used in the allocation.

• The customer invoice and the supplier invoice are separate documents. The customer invoice flow already knows the cost object, so its profit center is derived from the sender cost center.
• The supplier invoice is created from an incoming intercompany message (IDoc). This message does not include the receiver cost center from the allocation, so the system has no value to copy.
• When the cost center is missing on the supplier invoice line, the system uses the configured default cost center as a fallback, leading the posting to the default instead of the intended receiver cost center.

• There is no standard setting that makes the supplier invoice automatically pick up the exact receiver cost center from the allocation. This behaviour is delivered as designed.
• If each rebilling relationship can use its own dedicated expense account, you can map each account to its correct receiver cost center in the default account assignment configuration. This gives accurate results without any custom development, as long as the receiver can be told apart by account and company code.
