Vendor Debit Memo

Hi Guys

I have a scenario - where after MIRO and invoicing has happened, we do a return delivery to the vendor through MIGO {A02 return delivery, R02 material document}....

My question is, this does not impact the open AP postings right? and to make the open item reduced for the vendor, would I have to do an FB65 to make sure the open AP amount is reduced?

Or would doing MR11, facillate the correction of the FI postings?

Thank you
