A little twist on an old problem.  My Aging is more than my G/L.  Customer overpaid and through AR-M, we "sent" it to AP to write a refund check.  The customer never cashed the check (2 yrs ago), so I voided the check.  Now it is open in AP aging and I can't get it out.  Anything I do through AP-B will go to the balance sheet as well as the Aging.  Voiding the check did not automatically make a credit on the AR account; the AR acct still has a -0- balance.  Is the solution so simple I just can't see it?
