Hello Caetano,
Highly appreciates your reply.
May I know which parameters can I use in the BAdI to link within MO Reservation and PR MRP?
Previously I did use MO Save Event User Exit (IWO10009) to control it at Material level. Which means the system will not allow user to save the MO at IW32 (Delete component) if the material exist in Open PR.
But it had caused other issues and I had deactivated it and believed its not suit to control this.
BR,
Hafiz
