Moving linked tasks apart
The task you're moving was scheduled to start only after another task finishes. At some earlier time, a task dependency was created between these two tasks so that this task could not begin until the other task had been completed. By moving the task, you will remove this dependency. If this task is no longer dependent on the other task's finish date, you can remove the link and move the task with the Planning Wizard.
Note: Go to Link tasks in a project for additional information
Using the Planning Wizard, you can:
Remove the link and move the task to start on the specified day.
Microsoft Project will move the task to the specified day and break the link to the related task. The start date of the moved task will no longer be driven by the finish date of the other task.
Keep the link and move the task to start on the specified day.
Project will move the task to the specified day but keep it linked to the other task. Project will continue to adjust the start and finish dates of the moved task automatically to reflect changes made to the finish date of the other task.
Cancel the move and keep the existing link.
Project will not move the task. The task will start only after the dependent task finishes. Project will continue to adjust the start and finish dates for this task automatically to reflect changes made to the finish date of the other 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.
