About creating shipment-related invoices
The Order Entry application automatically creates shipment-related invoices when you run the Daily Shipment Journal (OE129). This program creates an invoice for each released shipment.
If the invoice is created in an unreleased status, you can make limited changes to shipment-related invoices in the Billing application. The parameters that you can change differ based on whether you can change the invoices at the header or line level.
