About modifying released journal entries
You cannot modify journal entries that are in a Released state. However, if you set up your company to allow these options, then you can unrelease released entries and you can also back out posted entries. You can select the Allow Unrelease of Released Entries option and the Allow Backout of Posted Entries option on the Journals form tab of Company (GL10.1).
Note: These options are available both for entries created
in the General Ledger and for entries interfaced to the General Ledger
from other Lawson or non-Lawson applications. However, there are restrictions
to which fields you can modify on unreleased entries. There are even
more restrictions for unreleased entries that originated outside the
General Ledger. These restrictions are the same as for base currency
journal entries. For more information, see the General
Ledger User Guide.
