Deleting (or reversing) a supplier payment that includes a discount
When you apply a supplier payment that includes a discount, MYOB Accounting Plus makes two entries: one for the money that you paid, and one for the discount that was applied to your purchase. When you then begin to delete or reverse that payment, a warning message alerts you that the discount was applied. To keep your payment records in balance, you must find and delete the discount entry after you've finished deleting or reversing the payment.
Be sure to note the amount of the discount shown in the warning message when you delete or reverse your payment. Then use the Find Transactions window to locate the discount that you need to delete. Use the features in the Card view to identify the purchase that you just deleted by the supplier and the date of the purchase. The discount that was applied should appear as an amount in the Debit column. To delete the discount, click the arrow to the left of transaction record to display the original discount entry. Then choose Delete Payment in the Edit menu to delete the discount.
