| phantom assembly (PP-MRP) |
A logical grouping of materials.
A phantom assembly is created in engineering to describe a number of components and manage them as a whole. The components in a phantom assembly are immediately placed in the superior assembly. Components in an assembly are first assembled to produce the header material. Then header material is placed in the superior assembly.
Example
The phantom assembly "set of wheels" contains the components "front wheel" and "rear wheel." The front and rear wheels are immediately placed in the "bicycle" assembly. The "light" assembly contains the materials "bulb" and "reflector." The light components are first assembled and then the light is attached to the bicycle.
