These are not OPEN payments/credit memos. These are payments/credits already applied to a posted invoice, that we'd like to display on the page/report. Basically, when you print a posted invoice, that has an applied-to payment or credit memo, it doesn't show up on the printed report, nor does it show up anywhere on the posted invoice page, to let the nav user know a credit memo or payment was applied to the invoice.
Thus when a customer asks for a new invoice, it prints for the full value of the posted invoice, and doesn't reflect any payments/credit applied-to it.
I'm trying to get this information to display in the posted invoices page, and then to print and deduct on the printed invoice.
Right now, we have to manually add a MISC item line, that states Invoice does not reflect payments/credits. and print a credit memo/payment and send that with the invoice.
