How do I reverse an up-front payment to suppliers/vendors (A/P Down Payment Invoice)

Question:

How can I reverse an A/P Down Payment Invoice once it is created?

Answer:

To reverse out an A/P Down Payment Invoice you will need to choose Copy To on the A/P Down Payement invoice and then choose A/P Credit Memo.  Ensure the new document is listing the full amount to credit. Also, make sure that the dates on the A/P Credit Memo are the same as the A/P Down Payment Invoice so that it is reversed out on the same date.
