AP Invoice Partially Returned

A business process is being revisited based upon 1099's this year. The scenario is an AP payment is issued. The receiver finds out that they got paid too much. They write a check and send it to us. We have vendors that may not be paid again. The finance team will do a journal voucher to put things back.

For example, issue a $100 check. Vendor a month later sends a check for $20. The 1099's are being ran, and the vendor is being reported for $100.

Is there a procedure to record the returned payment so 1099's are reporting correctly? Thanks.
