Material Classes
A material class is a grouping of common properties that can be applied to material resources.
Material classes can be directly associated with work process segments only. When you associate a work process segment with a work definition segment, the associated material class, and its properties, are made available to the work definition segment, and then to any work definitions that the work definition segment is associated with. A material class is distinguished from other classes through its properties, name, and description.
You can create a material class for paint. The class defines the paint by its individual components that need to be mixed together. To define paint as a material class, include all the corresponding elements for the paint that are needed, other than the color. By not including the color, the class can now be used with different colors of paint. The color itself is then defined by the material definition, process segment, or product segment.
