Action may cause a scheduling conflict because a summary task is linked but cannot move
The summary task that you're changing is linked to another task. At some earlier time, this summary task was linked to another task so that this summary task could not start or finish until the linked task had started or finished. However, the change that you're making now will constrain the summary task to a specific start or finish date. This may create a scheduling conflict, either now or later, because the linked task will no longer be able to drive this summary task's start or finish. You can avoid this scheduling conflict by canceling this action with the Planning Wizard.
Note: Go to Link tasks in a project for additional information.
Using the Planning Wizard, you can:
Cancel the action and avoid the scheduling conflict.
Microsoft Project will not change the task, and there will be no potential scheduling conflict.
Continue the action, setting the constraint, and allow the scheduling conflict.
Project will change the task and a scheduling conflict may occur. Project will not be able to adjust the task's dates to reflect changes in the linked task's dates.
If you don't want the Planning Wizard to display this information again, select the Don't tell me about this again check box.
