How To Fix GL138 - Ledger &, version & can be posted to or planned

GL138 - Overview

• Message type: E = Error

• Message class: GL - FI-SL Rollup

• Message number: 138

• Message text: Ledger &, version & can be posted to or planned

What causes this issue?

You want to update ledger &v1& with version &v2& with rollup data or
reset data using a reset set.
Since, however, ledger &v1& is also updated with actual or plan data
due to the actual and plan versions defined in configuration, the
rollup or resetting can lead to data inconsistencies.

System Response

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

How to fix this error?

If you want to use ledger &v1& for rollups only, inactivate the
indicator 'Ledger postng allowd' in the ledger definition.
If you also want to use a ledger that can be planned or posted to for
rollups, you should normally use a different version for the rollup.
