3833699 - Returning unused procured service parts fails for SVS1 in SVO1

When creating a return purchase order item for an unused non-stock service part that was procured for a Time & Material service order (SVO1) with item category SVS1, the system raises the following errors upon saving:

• Purchase Order item &1 still contains faulty account assignments.
• You can't change the account assignment object.

The account assignment category is inherited from the original PO item (category: Service Order), but the ServiceDoc reference field (service order / item) remains empty. Because manual entry of the account assignment object is blocked by design on return PO items, the user has no way to resolve the error through the UI.
