Are your vendors confused to which invoice you applied a credit memo? The credit memo might print at the bottom of the list on the check stub.
This is easily corrected.
Option 1: Change at each check run in Select Checks. Transactions – Purchasing – Select Checks.
At the bottom of the Select Payables Checks screen under Remittance: you can click the drop down next to List Documents and select Applied Order. The Invoice will print and then the applied credit memo will print immediately after it. The default setting of All Documents causes the credit memo to print at the end of the list.
Option 2: Change permanentlly in setup. Tools – Setup – Purchasing – Payables.
Change from All Documents to Applied Order. Click OK to save.
