My customer overpaid on account and I entered the total payment in AR-C which left a balance due.  I went to AR-M to enter a refund thinking this would clear the account.  Then went to AP-B entered and paid the voucher but when I went to check the AR-A to see if invoice was at zero the overpayment still shows up as open on account.  Please let me know how to fix this and then how to do this procedure properly.

We are using DBA version 2004.1 - really old.
