The material type selected controls the views possible for material.
For a material to be used in the system it needs to be created for each plant. Multiple views of a material are possible but at a minimum, the material needs to have a description and a base unit of measure assigned on the basic data view. Additional department views (i.e. Accounting, Sales, Purchasing, MRP, Warehouse) can be added at a later time by extending the material. As additional plants are added, a material will need to be extended to the plants before it can be used there.
