A PO finally Closed. There is an invoice with an unmatched line which is not accounted for, should it not reverse the balance back to the expense, but in this case it did not reverse when checked the AP Accrual balance.
Finally Close only reverses the outstanding encumbrances. It does not reverse outstanding accruals. the adjustments to accruals had to be carried out manually, using the Accruals write off process then generating a manual journal adjustment in the GL.
