Hi there; Please check that you do not have the" Lock fiscal periods ending on or before" or "Lock Fiscal periods starting on or after" with a wrong date. Go into Utilities, system manager, system setup, answer yes everyone is out of this company, General ledger, gl setup. Check that your date is not blocking you, if it is change the date. Myself I like using the Lock fiscal periods ending on or before then put in end of the month I wish to lock from.
