Use this procedure only if your transactions are changeable.
Note: Before deleting a payment recorded on an electronic payment transaction, you must delete the electronic payment transaction
If you delete a payment that was originally used to fully pay a purchase and any discounts for paying it off promptly applied to the purchase, a message will appear. If you receive this message, continue to step 2.
If no prompt-payment discount message appears, you're finished -- the payment is deleted.
Choose Delete Payment from the Edit menu.
