How to Assign Constraints in Primavera P6 – Project Management Software
Assigning Constraints in Primavera P6 Version 8.2
Number of Constraints per Activity
Two constraints are permitted against each activity. They are titled Primary and Secondary Constraint. After the Primary has been set, a Secondary may be set only when the combination is logical and therefore a reduced list of constraints is available from the Secondary Constraint list after the Primary has been set.
Setting a Primary Constraint Using the Activity Details Form
To assign a constraint using the Activity Details form:
- Select the activity requiring a constraint,
- Open the Status tab on the Activity Details form,
- Select the Primary Constraint type from the Date drop down list to the right of Primary:
Setting a Secondary Constraint Using the Activity Details Form
To assign a constraint using the Activity Details form:
- Select the activity requiring a constraint,
- Open the Status tab on the Activity Details form,
- Select the Secondary Constraint type from the Date drop down list to the right of Secondary:
The picture above shows that after a Primary Start On or After constraint is set there are only two Secondary Constraints available. After a constraint is set the date will have an asterisk “*” next to it.
- Start Constraints will have the “*” next to the Start Date, and
- Finish Constraints will have the “*” next to the Finish Date.
- Unlike P3 and SureTrak one does not have to display the Late Dates to see a Late Constraint “*”.
Expected Finish Constraint
This constraint is set in the dates Status area above the Constraints area and will only work if the Tools, Schedule…, , Use Expected Finish dates check box is checked.
