A cost center 1000 has been created with profitcenter 2000 in the master data.
Now we have defined a substitution that says: If the cost center is 1000 and if functional area is 3000, then profit center is 4000.
This substitution does not work because when we are trying to post a GL document with costcenter as 1000 and functional area as 3000, then the profit center is being reset to 2000 ( from the cost center master record) instead of 4000 (using substitution).
Any help on this issue will be highly appreciated.
