We have COPA standard derivation with incoming SO activated. We have also PCA substituions on Profit Centers -> 0kem, at SO creation and billing....
The thing is that when i create an SO, or Invoice... it seems that the system makes first substituion and then derivation... and we have porblem..
1) do you know maybe where to set up when substitution works ? at the beginning or the end.
2) The other thing is .. at what time system derive the COPA segment ? - only at SO creation or also at Invoicing ?
