Sage 100 ERP Cash ReceiptSage 100 ERP Consultant Tip:  Accounts Receivable Cash Receipts 

Question: Mike, we own Sage 100 ERP (formerly MAS90), when I am doing a Cash Receipt in Accounts Receivable I get the error “Invoice Already Being Paid”. But we have not paid this invoice yet, how can this be corrected?

Answer: First you need to determine whether or not the invoice has a balance. Follow these steps to determine if the invoice has a balance:

Sage 100 Tips and Tricks

    1. Go to Modules, Accounts Receivable, and Main. Double-click Customer Maintenance.
    2. Click the Invoices tab.
    3. Note any balances in the Invoice Balance column.

Second: If the invoice has 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 the ARWAR4 Utility.

Third: We always recommend doing this in a test company first to verify the problem can be solved and then complete in the actual company.  A copy can be done in the Library Master using the Copy Company feature.

Fourth: To complete, Use File, Run ARWAR4 as shown in the screenshots.
