About releasing electronic payment invoices
You batch release electronic payment (EP) invoices in the Billing application. When you batch release invoices, the Billing application performs settlement on each EP invoice.
You need to perform one setup procedure before the application will automatically run a batch program to accept EP information. You can batch release invoices using Invoice Batch Release (BL120), or release a batch using Invoice Entry (BL20.1). In order to receive EP information, you must set up a job name BL125-EP on EP Invoice Batch Release (BL125) for the same user name as the person who ran the batch release program.
Depending on the availability of goods when an order is placed, one specific order may result in many shipments. The Billing application creates a new invoice for every shipment that is released. The invoice only bills the customer for the items in the shipment.
