We are trying to utilize SAP's payment program for accounts receivables, specifically for EFT (electronic funds transfer) of a customer's incoming payment via an ACH file. We are using a custom "EFT workbench" that development created, but I know that SAP's payment program can be used for incoming payments as well as more commonly used for paying a vendor. I need an ACH file out of SAP with the customer's due invoices so that we may "sweep" their account. I have been over all of the payment program/payment medium workbench information and it is very slanted towards the vendor(outgoing) payments. Can someone point me in the right direction?
