Date Constraints on the Gantt Chart
Date constraints signal the earliest date that a task can begin. Once a date constraint is in place, the task can't be automatically rescheduled to a date prior to that indicated by this constraint. For example, if you create a finish to start dependency and then reschedule the first task to an earlier date, then:
-
If there's no date constraint, the dependent task is automatically rescheduled to begin immediately after the first task.
-
if there's a date constraint, the dependent task is rescheduled to begin as early as the date of the date constraint, but not before it.
On the Gantt chart, date constraints appear as solid vertical lines at the beginning of a dependent task.
For Finish-to-Finish (FF) dependencies, the date constraint is linked to the task's due date, which moves forward if the task duration is extended.This can be understood as moving the start date forward in case of Start-to-Start (SS) or Finish-to-Start (FS) dependencies.
You can add, remove, and edit date constraints on the table portion of the Gantt chart.
-
Navigate to a selected folder, project, or space and switch to Gantt Chart 1.
-
Click the gear icon 2 on the upper-left corner of the table portion of Gantt chart.
-
Check the Start Constraint box 3 in the drop-down menu that appears.
-
Click anywhere outside the window to see the column in the table.
-
Find the needed task and set the date constraint 4 in the Start Constraint column 5.
-
Navigate to a selected folder, project, or space and switch to Gantt Chart.
-
Create a dependency between tasks.
-
Use drag-and-drop to reschedule the dependent task to a different start date.
A date constraint is automatically added to the dependent task.
You can remove date constraints created on dependent tasks that are part of start to start or finish to start dependencies. To do this:
-
Navigate to a selected folder, project, or space and switch to Gantt Chart.
-
From here you can:
-
Click the task with the date constraint and use drag-and-drop to reschedule the task so that it begins immediately after (for finish to start) or on the same date as the preceding task (for start to start dependencies).
-
Extend the task’s duration so that it begins immediately after (for finish to start) or on the same date as the preceding task (for start to start).
