You don't need to do that and actually it is strongly advised not to. First
of all, the links describe logical process relationships between your tasks.
Whether you are scheduling from start date forward or finish date backwards,
you have to put up the walls before you put on the roof because the law of
gravity says you can't build the roof in midair and then stuff the walls in
under it. Physics drives it, not convenience or desired timing or even
schedule mandates. "Erect Walls" is the predecessor and "Apply Roof" is the
successor and the relationship is FS because of the inherent nature of the
building construction process and that's just the way it is.
Now, as for scheduling for a specific finish date. The behavior you say you
want is built right into Project without having to "get creative" with the
links. In the Project menu, you can select Project Information and there you
can designate "Schedule from finish date" and it will set up your tasks just
as you say you want. Now, the problem with that is that it will schedule
all your tasks to occur as late as possible to meet your required finish
date. Unfortunately that also makes ALL tasks in your project critical and
you have no margin for error (and there are ALWAYS unforseeable errors). If
just ONE of your tasks takes any longer to complete than you thought it
would or starts later than you'd planned on because, say, a resource called
in sick, you'll miss your required finish date. The far better way is to
schedule from the earliest practical start date forward, set a deadline of
your required finish date, and then tweak the schedule so you meet the
deadline. You'll probably find some tasks are critical and others not,
allowing you to concentrate your management skills where it really counts.
You can then make an informed decision "Do we start 1 Dec which gives us a 2
week cushion at the end or do we start 15 Dec and make sure Tasks 10, 17,
and 22 don't run late at any cost, ready to pull people off of Task 19
(which has a lot of float) if it turns out that one critical task runs late
and we need to move 'em to the delayed task to get it done back on
schedule?"
