Hi Atif,
Please verify the following IMG customizing step:
transaction SPRO -> Financial Accounting -> Asset Accounting -> Integration with the General Ledger -> Additional Account Assignment Objects -> Specify Account Assignment Types for Account Assignment Objects -> Company Code (CHOOSE) -> Depreciation Area (CHOOSE) -> Account
Assignment Objects
Here you need to add the FM object that is appearing in the error message.
I believe at least 'FKBER' for type 'APC Values Posting' must be inserted.
Regards, Vanessa.
