Foreign currency refunds not matching

Summary:

We have an order and payment in USD which needs to be credited off as we have received the money back into the bank account.

The money we have received is less that wat was originally paid out so need to make sure we get this accounted for.

If we received a refund for a GBP invoice we could add a credit to the system and match it to the PO then do a refund process to put this to fully paid

However, we don’t believe we can use the “Pay in Full” button on a refund which is what is causing an issue on this one as we do not have an option to put the conversion rate into the Refund pay in full.
