Define a cost element category for account &1 (controlling area &2)

What causes this issue?

Account &V1& is a profit and loss account. You assigned it to an object
in cost accounting (for example, a cost center, order, project, or profi
tability segment).
In this case, a cost element category must exist for account &V1& in the
determined controlling area &V2&.
See transaction <DS:TRAN.FS00>FS00</>, "Control Data" area.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Define a cost element category for account &V1& and post again or delete
the auxiliary account assignment to objects in cost accounting.
With profitability segment assignment, the error message is only
displayed when account-based profitability analysis is activated. Here
it may be a good idea to suppress the error message and ignore the
account assignment during the posting. This is particularly the case
when the posting is not only relevant for the result from the usual
business activity, for example for interest from cross-company sales in
a billing document. Such postings should not be taken into consideration
in the profitability analysis. In order to do this, you can define the
account &V1& in transaction <DS:TRAN.FCO_COPA_EX_N>FCO_COPA_EX_N</> (IMG

Exceptions for Postings to Profitability Segment)
