General Ledger Setting Enforce override period restriction was checked off

Uncheck General Ledger Setting to enforce override period restriction 

This setting simulates a hard month end close.  Having that option checked AND having the user with override permissions will still require that someone confirms the override in PO Entry in this case.  Hence why the stop in the program is stating that it manually needs to be posted.
