One of our Supplier Cards has a current balance of -$165 however when I go into the Purchases Register there is nothing listed in the 'Returns & Debits' tab. Also when I go to 'Pay Bills' it doesn't ask to apply a credit. I also ran the Supplier Ledger Report dated from 01/01/1900 to 31/12/9999 and the balance is -$165. Can you please advise how I find the transaction?
