How did you calculate weighted average in Primavera P6?

A WBS Element’s Schedule % Complete is calculated in a completely different way. You might expect it to be the rollup value of the underlying Activities (a weighted average for example). the three Activity values which are all less than% could never have a weighted average more than%. As you saw before, the Schedule % Complete of the Activities is time-based. However Schedule % Complete for WBS Elements is:1. Depended project costs and…2. Does not factor in any Activities’ Schedule % Complete values.

Schedule % Complete (Act) = ([Data Date] – [Baseline Start]) / ([Baseline Finish] – [Baseline Start])
