How to fix this error?

Check the changes in your system.

areas of a ledger group. Make sure that the fiscal year matches the
transfer year and the period is smaller/equal to the transfer period,
taking the fiscal year variant into account that is relevant for the
ledger group from an asset accounting point of view.
If <ZH>no</> legacy data transfer took place during the year, the
company code is deactive, or <ZH>no</> depreciation could be posted in a
depreciation area, the above-mentioned fields are <ZH>not</> ready for
