Reverse AP Check Posted to Next Month

At File / Open / Vendor, edit the Vendor and select the Activity tab.

Choose List under Payments. This will list the payments for the vendor.

Highlight the check to be reversed and select Void

When the Disbursement screen appears, select Void again.

A message will display stating the program cannot find the journal entry for that check. This is because the journal entry is a future journal entry not yet posted to general ledger.

Proceed to G/L / Future Journal Entries and delete the corresponding future journal entry.
