Netsuite documented that the Reversing Journal Entries cannot be edited after it has already been created. Prior to 2020.1 release, editing/updating Reversal Journal entries is possible via scripting but not in the UI. However, this shouldn’t be the case as per the official documentation. As of the latest 2020.1 release, the system behavior was corrected to follow what was documented as expected behavior.
To resolve the issue, update the fields we need to update in the Reversal Journal on the original Journal Entries since any changes made on the original entry affects the reversing transaction. We can’t change the date of the Reverse Journal Entry alone.
If we try to do this using script ,On Before Submiting the Journal, we couldn’t get the condition for Reverse Journal Entry “isreversal=T”, so couldn’t identify the Reseal Journals to update the values.
And if we try to set the same in after save and got the error “REVERSAL_JOURNALS_CANNOT_BE_EDITED_OR_RESUBMITTED_”.
So we conclude that there is no option to change a Reverse Journal Entry Record different from the original Journal Entry.
