a supplier paid a credit note by cheque

Hi all

Sorry if this question has come up a lot in the past, but I can't find it in the recent posts.

As briefly as possible, a supplier sent me an invoice, I entered it, I then entered a cheque to pay it off in full. The supplier then sent me a credit note for part of that invoice, followed shortly after by a cheque from them to clear it. How do I enter a cheque from a supplier to match against a credit note?

Thanks in advance for your help. Ronaldo
