Facility_Equipment_Flag	CODE NA	A flag to denote whether a given facility should be treated as a facility (F), a piece of equipment (E) or both (B). A facility labeled as F represents a role (e.g. ESP) played by physical piece(s) of equipment and would not have attributes like serial number, manufacturer etc. It can be related to the physical pieces(s) of equipment using Facility_Composition. The individual physical pieces can be replaced if they need to be, without changing the facility. A Facility labeled as E represents a physical piece of equipment (e.g. Drill Pipe) which is normally used in the context of an activity and would not be permanently installed. A facility labeled as B represents both a physical piece of equipment as well as the role played by it. If this kind of Facility is connected in the network and stops working and needs to be replaced, then all connections to this Facility are expired and new connections are made to the replacement facility.
