If you want a payer based discount on invoice list only. This is what you will need to do:

discount is factoring discount. But it is payer based discount.
IMG - Sales and Distribution -> Billing -> Billing documents -> Maintain conditions for invoice lists ->
Maintan pricing procedures
2. RL00 uses access sequence RL00 and condition table 7 which is sales organization/distribution channel/divison/customer

configuration.
3. In the appropriate place in your pricing procedure, add in condition type RL00(or one you created). Be careful to copy the
requirement routine and condition base value assignments from pricing procedure RVAA01.
