critical path disappears

I have all tasks linked and the critical path is showing . Then I set a must
finish on constraint on the last task and the critical path disappears.

I work around it setting a deadline on the final task so my critical path
shows - any explanation of why this happens?

Thanks!

DianneZ --

The Critical Path consists of all tasks whose Total Slack is 0 days. When
you set the Must Finish On constraint on the last task, was the MFO date
later than the original Finish date for the task. If so, you created slack
in the schedule. To determine if any tasks have slack, click View - Table -
Schedule and then pull the split bar all the way over to the right so you
can see the Total Slack column. If you see Total Slack greater than 0 days,
then the tasks are not Critical. Hope this helps.
