Re: MRP Run based on material reservation and material type.

1. Create New Material
2. Assign MRP type as PD
3. Create one Maintenance Order for that material
4. Reservation will be created
5. Now run MRP in MD02 for that material
6. It will generate PR

Get the inputs from your PP / MM consultants on maintaining the MRP view data in Material Master, in MD02 & Configuration for MRP run.
