• Message class: GU - FI-SL utilities

• Message number: 637

• Message text: Postings to &1 during the run may lead to incorrect results

What causes this issue?

You want to perform a balance carryforward for ledger &V2&.
If postings are made to the old fiscal year when the balance is actively
carried forward (also possible by allocations or rollups), the results
of the balance carryforward may be incorrect.
Due to conceptional reasons and for performance reasons, the system is
unable to ensure that postings are not made to the old fiscal year when
the balance is actively carried forward.

System Response

A corresponding information message is always issued for security
reasons.

How to fix this error?

Make sure from an organizational perspective that when the balance is
actively carried forward, postings are not made to the old fiscal year
&V1& (for example, by starting the balance carryforward in a
posting-free period).
If postings are made to the old year, however, and the results of the
balance carryforward are incorrect, you can repeat the balance
carryforward at any time when postings are no longer made to the old
fiscal year. The results will then be correct.

Procedure for System Administrators
