Work Confirmation Accepted - Receipt and Accrual

Hi,

Using Complex Work Procurement, if the supplier requests the Work Confirmation and the buyer (company) accepts the confirmation, is isupplier or procurement creating the PO receipt? I need to know if accepting the confirmation an accounting entrie is created.

I believe that if you accept the confirmation the work accrued so the cost must be recognized so journal entires must be made.

Thanks!
