Making changes in the timephased portion of the view causes a conflict with another task
The timephased edit will cause one task to finish after the start of the task to which it is linked.
Using the Planning Wizard, you can:
Keep the timephased edit and ignore the link.
Microsoft Project will keep the edits you made to the timephased portion of the view and ignore the link between the tasks. It will do this by putting a constraint on the task that you're editing.
Ignore the timephased edit.
Project will remove the timephased edits you made and will not change the links or constraints that are applied to the tasks.
If you don't want the Planning Wizard to display this information again, select the Don't tell me about this again check box.
