How can I post scrap to the vendor cost center or QM order when IQC UD

The raw material from overseas  vendor ,with one or two of ten scrap and the scrap   will  settle on vendor cost center or QM order,

I would  like to post the scrap inventory to the vendor cost center or QM order when IQC UD.Please don't tell me the standard way is to return or block the material and return to the vendor, it will keep the purchase order open can't be closed.

.

Thank you!
