partner functions in sales orders
Partner determination has been set accordingly. But I still encounter the issues below in the same order. Moreover, those issues just occur in either order header level or item level, such as issue 2 - RE & WE can be changed in order item but can NOT be changed in order header.
My request is to prevent from changing partner, i.e. cannot change customer code manually in ordes. Currently, sold-to party, bill-to party, ship-to party and payer are the same. Pls help. Thx.
Issue 1: Partner function RG (payer) can be changed to other customer code manually in order header.
Issue 2: Partner function RE (bill-to party) , WE (ship-to party) & RG can be changed to other customer code manually in order item.
