A deadline might affect scheduling after all
There are two instances in which a deadline can indeed affect task scheduling. The first is if you enter a deadline that falls before the end of the task's total slack. The total slack is recalculated using the deadline date rather than the task's late finish date. If the total slack reaches 0, the task becomes critical.
The second instance is if you set a deadline on a task with an As Late As Possible con straint. Suppose the task is scheduled to finish on the deadline date. However, if any pre decessors slip, the task could still finish beyond its deadline.
For more information about the critical path, slack, and late finish dates, see "Working with the Critical Path and Critical Tasks" on page 251.
