&1: ANLC values without general ledger assignment in the open year

What causes this issue?

ANLC values without general ledger assignment in the open year

System Response

This consistency check validates to what extent annual values are
covered in the original ANLC table by the balance carryforward year of
the general ledger.
The reason for this error situation can be, that the general ledger
balance carryforward was not processed to the same year as the asset
management. Another reason can be, for example, a fiscal year change for
the fixed assets was already carried out for two years in the future and
closing operations have been reversed.
Based on the existing data, the values from asset accounting are
migrated, while balance carryforward values for G/L accounts are not
migrated. This may lead to severe errors.

How to fix this error?

In the original system, make sure that the balance carryforward to the
identical years has been performed consistently in both:
In asset accounting and the general ledger for all ledger.

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