ap debit memo

Help me clarify if I enter debit memos in AP voucher: over paid supplier and receive check with the difference

using the AP debit process

·        it will credit the open amounts for the supplier

·        if no open amounts

o   does this create an amount that the next time make a payment to the supplier it subtracts that amount for me

§  if yes if this is a onetime supplier how do I get to my AR

·        does it create an AR batch I need to post to put back into my bank account

·        is the amount subtracted from the suppliers 1099 reporting amount
