Overview

This structure is used to uniquely identify a Project Task. Project Tasks can be identified by an ExternalSystemIdentifier or ProjectTaskUid. When specifying a PwsProjectTaskRef as an input to a web service, you may specify one or both the ExternalSystemIdentifier and ProjectTaskUid. However, if you do specify both, they must both refer to the same Project Task or the Project Task reference will not be considered valid. When a PwsProjectTaskRef is returned in the response to a web service, both the ExternalSystemIdentifier and ProjectTaskUid will be populated, and guaranteed to refer to a single Project Task.
