Add a task constraint

You can use constraints to force a shift in the schedule honoring the constraint type. The constraint type is indicated by a red marker on the Gantt chart task bar.

Procedure

1. Select a task in the task table.

2. Choose Schedule → Task Constraints.

3. From the Task Constraints dialog box, choose a constraint type:

   Constraint	Behavior	Gantt chart indicator
   No Constraint	No constraint applied	No red arrows
   As Soon As Possible	Works with task dependencies to schedule a task as soon as the task dependency and other scheduling considerations allow	Red arrow pointing left
   As Late As Possible	Works with task dependencies to schedule a task as late as the task dependency and other scheduling considerations allow	Red arrow pointing right
   Fixed	Fixes the task duration; schedule dates cannot be changed	Red arrows pointing both left and right

4. Click OK.
