There is already a constraint on this task that conflicts with the timephased changes you're trying to make
The task already has a constraint. To keep the timephased edit, the task constraint must be changed to a different constraint.
Note: Go to Set a task start or finish date (constraint) for a task for additional information.
Using the Planning Wizard, you can:
Keep the timephased edit and change the constraint.
Microsoft Project will keep the changes you made to the timephased portion of the view and change the constraint on the task.
Do not change the constraint.
Project will remove the timephased edit you made and will not change the constraint on the task.
If you don't want the Planning Wizard to display this information again, select the Don't tell me about this again check box.
