Hi Susan,
If a Check is Reversed in AP, not only is the invoice unpaid (as Bruce suggested), but GL transactions are generated with the reversal (as indicated on the Reconciliation Posting Journal) and will update the GL accounts when the AP transactions are retrieved into GL and the batch posted there. Perhaps you haven't yet posted the GL batch yet?
In BankRec, you should edit all of your banks that integrate with AP and look for the option to 'Update Payables Check Reconciliation'. Set this option to 'Pending' instead of 'None'. That way, when you process a reconciliation in BankRec, the same status changes to the AP checks will automatically be written to AP, thus better avoiding the possibility that different check rec statuses are applied in BankRec versus AP.
Once a check rec status change is posted, it cannot be undone. You will need to repay (or adjust) the invoice in AP, and for any other apps where information can be retrieved (ie BankRec and GL), you need to decided whether the generated entry must be posted or deleted. If that program has correct information already, then the entry from AP should be deleted. Make a backup of your company data prior to making these changes, in case you post something you really didn't want to.
