Outside Order - Missing Buyer ID in header (PHANBY)

Dear JDE Community,

« Outside Operations » (type « OO ») do not assign a Buyer ID in the PO Header (PHANBY) when generated from a Work Order. The right Buyer ID is only displayed at PO details level (from Item Branch IBBUYR).

Here below the current logic : P3411 (MRP Message) => P48013 (WO generation) => R31410 (order processing) => P4310 (PO creation based on the WO routing)

As the applications (R31410 and P4310) are customized, I am not sure if we are facing a regression or if it's a standard behavior.

Just to let you know that we do not face this issue when generating standard OP order from MRP messages. In that case, the Buyer is rightly retrieved and assigned to the PO Header.
