How does physical percent complete roll up the task hierarchy?

The physical percent complete value for lowest-level tasks is used, along with baseline planned cost or effort, to calculate earned value cost and effort.

Earned value cost and earned value effort roll up the task hierarchy. At each level, earned value is divided by the baseline planned amount to derive physical percent complete. The Primary Physical Percent Complete Basis option for the project plan determines whether baseline planned cost or effort is used.

Tip: You can view physical percent complete calculated using both cost and effort for each task. However, the Primary Physical Percent Complete Basis option determines which value is used for other financial activities and calculations.
