Edit Dates and Constraints Page of the Activity Form Page
Overview
Use this page to edit dates and constraints for the activity.
Screen Elements
Start Date option
Determines whether the activity has started.
Start Date field
The date work for the activity is scheduled to begin. For started activities, this is the actual start date. For not started activities, this is the planned start date until the project is scheduled. When scheduled, the start date field is set to the remaining early start date.
Finish Date option
Determines whether the activity has finished.
Finish Date field
The date work for the activity is scheduled to finish. For completed activities, this is the actual finish date. For not started and in-progress activities, this is the planned finish date if the project has not been scheduled. When scheduled, the finish date field is set to the remaining early finish date.
Suspend Date field
The date work has stopped on a given activity for an unknown, but temporary, period of time. For example, an event might force an activity to be interrupted or resource constraints might put an activity on hold.
The suspend date must be later than the actual start date, which the activity must have. Activity progress can resume when the Resume Date is set. The suspend/resume period behaves like a non-work time on the activity calendar or resource calendar for task and resource dependent activities.
Resume Date field
The date when a suspended task or resource dependent activity is resumed. The resume date must be later than the suspend date and earlier than the actual finish date.
The suspend/resume period behaves like a non-work time on the activity calendar or resource calendar for task and resource dependent activities.
Duration Percent Complete field
The percent complete of the activity duration. The type of percent you see depends on the percent complete type you select for the activity in the General section of the Activity Form page.
The planned duration is taken from the current plan, not from the baseline.
Calculated as (Planned Duration minus Remaining Duration) divided by Planned Duration multiplied by 100. Always in the range 0 to 100.
Primary Constraint list
Determines the primary constraint on the activity. Choose from one of the following options:
- Start On: Imposes the specific start date you choose. The Start On constraint can delay an activity's early start or move forward an activity's late start to satisfy the constraint date.
- Start On or Before: Defines the latest date an activity can start. This constraint only affects late dates and might decrease total float. When calculating a schedule, P6 imposes the start on or before constraint in the backward pass only if the calculated late start date will be later than the imposed date
- Start On or After: Defines the earliest date an activity can begin. This constraint affects only early dates. When calculating a schedule, P6 imposes the start on or after constraint in the forward pass only if the calculated early start date will be earlier than the imposed date.
- Finish On: Imposes the specific finish date you choose. The Finish On constraint can delay an activity's early finish or move forward an activity's late finish to satisfy the constraint date
- Finish On or Before: Defines the latest time an activity can finish. The finish on or before constraint affects only late dates.
- Finish On or After: Defines the earliest date an activity can finish. The finish on or after constraint reduces float to coordinate parallel activities, ensuring that the finish of an activity is not scheduled before the specified date. It is usually applied to activities with few predecessors that must finish before the next phase of a project.
- As Late As Possible: Imposes a restriction on an activity with positive float to allow it to start as late as possible without delaying its successors. When calculating a schedule, P6 sets the activity's early dates as late as possible without affecting successor activities.
- Mandatory Start: Imposes the early and late start dates you choose. P6 uses the mandatory early start date regardless of its effect on network logic. A mandatory early start date could affect the late dates for all activities that lead to the constrained activity and all early dates for the activities that lead from the constrained activity.
- Mandatory Finish: Imposes the early and late finish dates you choose. P6 uses the mandatory finish date regardless of its effect on network logic. This constraint affects the late dates for all activities that lead to the constrained activity and all early dates for the activities that lead from the constrained activity.
Primary Constraint Date field
The date associated with the primary constraint, if the activity has a primary constraint assigned.
Secondary Constraint list
Determines the secondary constraint on the activity. Available only when the Primary Constraint is not Start On, Finish On, Mandatory Start, or Mandatory Finish. Choose from one of the following options:
- Start On or After: Defines the earliest date an activity can begin. This constraint affects only early dates. When calculating a schedule, P6 imposes the start on or after constraint in the forward pass only if the calculated early start date will be earlier than the imposed date.
- Finish On or After: Defines the earliest date an activity can finish. The finish on or after constraint reduces float to coordinate parallel activities, ensuring that the finish of an activity is not scheduled before the specified date. It is usually applied to activities with few predecessors that must finish before the next phase of a project.
Secondary Constraint Date field
If the activity has a secondary constraint, this is the date associated with it.
This field is only available if a primary constraint is already entered.
Expected Finish field
The date the activity's primary resource expects the activity to end.
Only the primary resource can edit this field if the activity has started.
