AP invoice unreceived line then PO cancelled

Hi,
I’m trying to figure out how can I clear un-received line invoice in Invoice/Match window.
Here is the situation.
A supplier PO is crated, the supplier send an invoice for payment 100% and is posted as unreived line, a payment is made to the supplier, the the supplier cannot fulfill the order and we cancel the order and ask for refund.
Any advise?
Thanks,
