How do I show multiple critical path?

[Uncle Duck]

My project has three Milestones, and I'd like to analyze the critical path to
each of these Milestones. I can see the overall critical path, but I'd like
to see the others. I've gone to the Calculation tab in Options, and checked
"calculate multiple critical paths", but it does not work. I know I could
just create three different project files, but I'd rather keep them on one
file.

Uncle Duck,
My guess is that multiple critical paths is not working because each of
your milestones has a successor. In other words, the interim milestones
are part of the overall network and do not define three individual
independent networks.

Potential solutions are as follows: 1) Set the milestones up so they
effectively define the end point of their respective tasks, 2) use the
old fashioned method and calculate three successive critical paths. To
do the latter, apply a finish-no-later-than constraint to each milestone
in succession. When a constraint is set on the first milestone the
critical path leading up to it is its critical path. When a constraint
is set on the second milestone (and removed from the first), the
critical path will be to that milestone, and so forth. Not as convenient
but it does work.

You might want try setting deadlines to
1) the the dates of the milestones or
2) to equal the finish dates of the task before the milestones
