Occassionally when printing the Accounts Receivable report "aged trial balance" using "calculate at" the end of the previous month, the subledger report does not reconcile to the control account. Normally we don't worry about it because it always reconciles after the cutoff date. But it happened at our year end and the external accountants convinced me to investigate. So I traced one transaction and even though "customer transactions" shows a balance outstanding, this balance does not appear on the subledger report. Is there another report that is date sensitive that we should be using instead? Or are we doing something wrong?
