Client posted 2 invoices in AR to 2 different customers but with identical invoice numbers (an error). AR accepted it. It was posted in AR. Cash was successfully applied to both invoices and the batch was posted successfully in AR. The problem occurs in Bank Rec. Bank Rec consolidated the 2 invoices into one under the first customer`s name and showed all the invoice amounts correctly but as though the 2 invoices were one. It applied cash to the first one, but left the second one as unapplied cash.

Any idea what caused this and how it could be prevented.

A small number of invoices are created outside of Adagio and consequently do not always follow a sequential numbering system.

AR 9.0B (100910)
BK 8.1B (100506)

Was a "payment method" used when the cash receipt was recorded? What was the document number for the cash receipt for each client? I'm assuming that the cash was entered in a separate cash bactch after the invoices were posted.

Andrew, I just discovered that these were both misc. cash receipts - no customers. This explains everything. Sorry for the false alarm.
