Hi,
1. The change should be only in OKGB.
2. In column "Masked Cost Element" enter "033336001".
If you enter "03++++++++" all accounts with leading dight "3" will be included in the WIP
calculation & settlement.
3. As the balance for 33336001 is 0 for order in question it doesn't really matter how you assign it.
You can assign it to "COP".
Regards,
Szymon
