Create Payment group flow

Hello,

Can someone please help me with the flow of create payment group program J04570. Basically I want to understand flow of how the payments are created in the Payment control group file F04571.

Appreciate your help.

Thanks,

Use Program R04570 to create Payment Groups for Automatic Payment processing.
1. Set up Vendor Bank in P0030
2. Set up P0417 to default based on Payment Instrument.
3. Process your Vouchers to appropriate status.
