RRB- Quantity from Project and rate from sales order

Hi All,

I got scenerio in my project where project is having resource related billing. Now ap per the client requirement, we have a sals order and projects. All prjects are software projects. Now my requirement is client is looking for a system there billing can be done at projet and resource level. which means if project is having 50 confirmed hours. In - dp91 one debit memo requiet should be created with 50 hours and rate should come sales order.

Means if on a project 50 hours has been confirmes than in debit memo request 50 hours should come from the prject and rate to be billed should come from sales order.

Kindly suggest.

Regards
