Moving a linked task before its predecessor and onto a nonworking day
The task you're moving was scheduled to start only after another task (its predecessor) 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.
In addition, you're moving the task so that it starts on a nonworking day. If you begin or end a task on a nonworking day, Microsoft Project cannot schedule any work to be done on that task during that day. The task will not actually start until at least the next working day. In the Gantt Chart view, nonworking time is indicated by gray vertical bars by default.
If it is still important that this task not start until the other task finishes, you can cancel the move with the Planning Wizard.
Note: Go to Link tasks in a project and Set the general working days and times for a project for additional information.
Using the Planning Wizard, you can:
Cancel the move and keep the task link.
Project will not move the task. The task will start only after the predecessor task finishes. Project will continue to adjust the start and finish dates for this task automatically to reflect changes in the finish date of the predecessor task.
Break the link and move the task to start on the next working day.
Project will move this task to the next available working day after the date you specified and break the link to the predecessor task. The moved task will start before the other task finishes.
If the task must begin on the date you specified, you can make that day a working day and then move the task to that day.
If you don't want the Planning Wizard to display this information again, select the Don't tell me about this again check box.
