Customer statement doesn't reveal outstanding credits

ScottSilverstine

I have a customer with a credit invoice which represents an advance payment. This same customer has another open invoice for a charge for products that were delivered. I recently generated a statement for all unpaid invoices. The credit invoice fails to show up on the statement. As the credit as yet to be applied against the open invoice of the products that were delivered I would expect that both of these invoices would appear on the statement but they don't.
