Overview

This structure contains the unique key fields associated with a project time baseline. Project time baselines can be identified by and ExternalSystemIdentifier or ProjectTimeBaselineUid. When specifying a PwsProjectTimeBaselineRef as an input to a web service, you may specify one or more of these three fields. However, if you do specify more than one, they must all refer to the same project stage or the project stage reference will not be considered valid. When a PwsProjectStageRef is returned in the response to a web service, all three fields will be populated, and guaranteed to refer to a single Project stage.

Elements

Element	Data Type	Required?	Description	Sample Data
ExternalSystemIdentifier	String	One of ExternalSystemIdentifier or ProjectTimeBaselineUid is required	The external system identifier is a unique identifier for a project time baseline (may be null, but once set can only be updated to a different, non-null value)
ProjectTimeBaselineId	Int32	No	The project time baseline Id is a unique identifier for a project time baseline. For internal use only.
