|Description||string||CIM_ElementHasBeenFRUed is an association between two Physical Elements that indicates that the entity referenced as the ReplacedElement was swapped for or replaced by the entity referenced as the ReplacementElement. The association is many to many, conveying that an element might require several other elements to replace it, and vice-versa. The typical scenario, however, is that one PhysicalElement replaces another. It might not be possible to instrument or manually determine that an element actually replaced (FRUed) another. This determination is especially difficult if the original element is discarded. However, if this information is available, then this association describes this scenario.
