Base Finish Time is used to
calculate current project schedule. Note that in most cases,
Finish Time is calculated automatically
based on a task's Start Time
and duration. If you update the Finish Time, the
Constraint is set to "Must Finish On". See "Start, Finish
Times, and Constraints" for more details.).
