3607791 - Investment Project settlement with additional sender line item

When performing an investment project settlement to an Asset Under Construction (AuC), a separate sender line is generated with a cost element not maintained in the allocation structure.

SAP S/4HANA Cloud Public Edition

This issue occurs due to a vendor down payment posted to the project.

For more details, please refer to the SAP Help documentation:
Vendor Down Payment | SAP Help Portal

Note:

• If the down payment is linked to a Purchase Order (PO), the cost element used will correspond to the one maintained under the Account Assignment tab in the Purchase Order.
• If the down payment is not linked to a Purchase Order, the system will use the default General Ledger (G/L) account (e.g., 65001000).

Check below KBA for more details.

As mentioned in the help document above:

You post the down payment to an investment project (WBS element) and settle it to an AuC. Before you can carry out a final settlement, you must have cleared the down payment with the invoice. You can then settle the AuC to the final asset.
