In Peachtree 2002 an invoice was paid using tasks/payments and it was done incorrectly 3 times. The invoice now shows partial payment, however the three checks do not show on the list to void, nor are they in the check register. The payments were deleted but the invoice still shows partially paid, with a balance 3 times higher than the original invoice. How can I delete the invoice and all transactions associated with it without going to a backup tape for the previous days work.
