1- Critical path might have changed so the list of critical path activities might differ.
2- If using resource constrained schedules P3 will yield wrong float results and will show discontinuous critical path. Therefore under resource leveling you will be better off assuming all activities are critical, don’t ever believe available float as shown is true for all activities. In this case better get software capable of showing resource critical float.
3- If not using resource leveling you can try with a filter to select activities with critical float for the actual job and the baseline. After you filter to include both critical path activities then you can display your required column fields for the actual job and the baseline. The same you can do at the Gantt chart, you can define your baseline bars to be shown using the format bar functionality.
Better get software capable of showing resource critical float:
Schedule a 2 activities network, not tied one to each other by precedence logic but sharing a limited resource. For example:
Activity A - 5 days
Activity B - 5 days
Both activities sharing Resource A as a common resource.
Most software under resource leveling will schedule A and B at different time, the first one depending on your priorities selection. This is ok up to this point, but the problem is most will show float of 5 days on the first activity while a delay in this activity will delay the completion of your schedule.
Imagine that you as a Project Manager look at the available float as per your CPM schedule and start paying attention to those shown as critical and even start moving resources from those showing some float as to keep under control those showing no float. Because most software under resource constrained schedule will show the wrong float for resource critical activities you most probably will end up moving resources precisely from the wrong activities. You either will discover too late it was wrong or start doubting about the CPM float display. Well better start doubting about the CPM float display and either buy a glass ball or software capable of showing resource critical float.

Thanks for the reply,
Just as we could compare in P6 the BL Total float and total float,Is there any option in P3 to do the same..(not considering individually)
Is there any option in global change..
With Thanks & Regards,

Hi
you have check two programmes critical paths individual way
