Hi
You can add a condition and assume it is for one BU/PC. But you cant actually indicate in Sales Order any BU/PC at the Condition Level
We had a similar requirement and we handled it this way..
You have a DIVISION field in Customer Master as well as Material Master.. In COPA, DIVISION is always populated from Mat Master...
So, we added a User Defined Char in COPA (WWXXX) and create a derivation rule to derive WWXXX from Customer Master..
The Division in Mat Master can have Factory BU and the one in Customer Master can have the Sales BU. This will be a clean approach
