We are a municipal government running R/3 Enterprise 472 with Public Sector. We'd like to "turn on" the account assignment element functional area, however, we do not want to implement Fund accounting. We've ticked the functional area account assignment, created a derivation rule for the functional are to be derived from the cost center master. When we try to post a journal entry, the functional area is derived but it won't populate in the functional area field. Upon posting we get an error stating that the functional are field cannot be blank/space. So it is deriving but not "sticking". Anybody out there got any clues as to what we've missed.
Thanks in advance
