Actual Start

Actual Start field

If work has started, the date work on the activity, WBS, project, or EPS began.

If resources (labor, nonlabor, or material) or roles are assigned to the activity, the actual start date is the earliest among all the resource or role assignments.

For a WBS, project, or EPS, the actual start date is the earliest actual start date among all activities within the WBS, project, or EPS.

When P6 is integrated with Primavera Unifier, the Actual Start date might have been imported from Primavera Unifier rather than calculated by P6.
