Q.  After running MRP, it recommends the creation of a Phantom Assembly.  How is this possible?

A. It's not. The MRP is only showing you what the source of the requirements for the parts contained in the phantom are. Without showing this information, users become lost trying to understand where the demand is. Knowing that a part is used in the phantom, the user can then look up the requirements for the phantom to ascertain the parent requirements. MRP recommendations for phantoms may be safely ignored.
