Account posted with account assignment has to be defined as a cost element.

There are several ways to solve the error:

1. Change the account to a cost element, you can do this via APP 'Manage G/L Account Master Data', you may change the account type as P, for example, for Primary Cost or S(for Secondary Cost) and define a Cost Element Category accordingly.
2. If account cannot be changed as a cost element, you may consider to replace the account with another cost element using Configuration Activity / SSCUI '100297 - Automatic Account Determination' for transaction KDM/KDR.
3. If above 2 ways still not acceptable, and if the account assignment is Profitability Segment and you do not want the postings occur to profitability segment, you may also consider to map the account in Configuration Activity / SSCUI '105626 - Exceptions for Postings to Profitability Segment'.
