So in March we paid a foreign exchange invoice (euros) but in April payment was returned to us for a different amount, Vendor is set up in Euros

Original transaction was 2 invoices paid totaling 49.20 Euro, with an exchange rate of 1.5107582, so totaling $74.33

Payment was returned to us in Canadian for $72.63, so an new exchange rate of 1.4762195.

How do I put amount back on Vendors account with showing a debit to our bank for $72.63?

Thank you in advance
