Q: We use the Accounts Receivable Module for Sage 100 ERP (F/K/A MAS90). When doing a Cash Receipt I get an error, “Invoice Already Being Paid”. But this is incorrect. How can we fix this?

A: The first step is to determine whether or not the invoice has a balance. Determine this by

  1. Modules>Accounts Receivable> Main- double click “Customer Maintenance”
  2. Click Invoices Tab
  3. Check for any balances in the Invoice Balance column

If there is a balance, the “Payments Today” field in the Open Invoices File (AR4) is set incorrectly. This indicates that the invoice is already being paid. To correct this you will need to run an ARWAR4 Utility.

It may be a good idea to do this first with a test company to avoid incorrectly altering an account. A copy can be done using Library Master Copy Company feature.

To complete, use File>Run> ARWAR4 as shown


Click Yes, and you should be complete.
