Tagging a Refund from Supplier

Hi,

Thanks for the advice, however, there is a bank transaction recorded for the purchase (6076 17NOV15 , 8007160705 US), so surely I should be able to tag the refund (6076 26NOV15 , 8007160705 US , REFUND) against the purchase.

Both are listed at the same £ cost, so my understanding was that tagging a refund against a purchase theoretical balances the bank, is this correct?

Regards,
Andy
