Hi Maheswaran,
Yes, you should have PR00 ( similar Z condition) to get sales price from Condition records
As I observed , Billing Form has separate Usage (SENI) and DIP profile has separate Usage (SEIN)while determining
,
This Billing Form is not controlling the Actual cost flow to debit memo request
EK02 can be used but it will have only planned cost and if you want Sales price and Mark up, new condition type should be added again
