When an external system needs to get crew details for one Crew, or all Crews, or the Crew needs to be indicated assigned, un-assigned, dispatched, un-dispatched, arrived, available, unavailable, active, in-active, or suspended from an event in or independent from an event in Oracle Utilities Network Management System; the external system will send a crew update message with the event id to Oracle Utilities Network Management System. The VERB of the CrewUpdate_001 XML message will indicate the state or action to be triggered by the message. Creating, deleting and editing crews is also supported by this flow.
