In this article, you learn about Percent Complete Fields in Primavera P6 (Duration Percent % Complete, Unit Percent % Complete and Physical Percent % Complete)
Types of Percent Complete Fields In Primavera P6
1-The Duration % Complete
You may expect Duration % Complete to use a formula similar to the following:
Duration % Complete (Not used in P6)=[Actual Duration] / [Planned Duration]
Duration % Complete (Used in P6) = ( [Original Duration] – [Remaining Duration] ) / [Original Duration]
If the Remaining Duration is greater than Original Duration, the result would be a negative value, but the Duration % Complete will be zero.
Example: We have an activity with an original duration of 30 days. 20 days have passed & we estimate it to finish in 23 days (yes, it’s much longer than we expected initially). The Original Duration does not change automatically after the activity’s start.
Original Duration: 30d
Actual Duration: 20d
Remaining Duration: 23d
While the intuitive Duration % Complete = [Actual Duration] / ( [Actual Duration] + [Remaining Duration] )
= 20/(20+23) = 46.5%
How to Use Duration Percent Complete in Primavera P6:
When you enter a value for a percent complete field in Primavera P6 in the Activity % Complete column or directly into the Duration % Complete column. Primavera will automatically calculate the Remaining Duration for this activity. Or you can enter the Remaining Duration value and let Primavera P6 calculate the percentage.
2-The Units % Complete
When you add Assignments and Expenses to Activities, the budgeted units will be calculated; when you add actual units, the combination of planned and actual units will make the Units % Complete through this simple and intuitive formula
Units % Complete(Used in P6) = [Actual Units] / ( [Actual Units] + [Remaining Units] )
3-The Physical % Complete
Units % Complete & Duration % Complete is not appropriate for some Activities; in this case, you can use Physical % Complete. The value of this field shapes in one of these ways:
1-By manually entered values
2-By Activity Steps
