You do not necessarily have to enter a material on this screen. For example, you can select all materials for one planer group or in one plant.
Note that the material cannot have the material type KMAT. The procurement type cannot be external procurement. The procurement type is on the MRP 2 tab page of the material master.
The system schedules the routings and updates the master records of the selected materials. It produces a results list with the scheduling results.
