1. I created sales order with BOM ie:
ZTAQ-- Main item -- priced
ZTAE-- sub component -- text
2. Assigned Bill plan to ZTAQ for down payment scenario.
3. When I created ZFAZ for downpayment request: getting error as 000020 For down-payment requirements, only billing rule 4 or 5 can be used.
4. Bill plan is only assigned to ZTAQ
