Thanks Mr.Anil,
But dont i have to enter the correct date and time when the external service is done.
So here only after 25 PRs are generated shall i create 1 PO for these and 1 SES with 25 lines.
But by then all service are executed because it takes a gap of 3 months to get 25 PRs.
In Workorder i need to notify the exact date of completion of oder .
