Create critical path for “any activity”

In Primavera when we use the default "Critical" filter, it will show the critical path for the whole project (for the last activity).

How about if we want to show critical path for an activity which is somewhere in middle of project, not the last one.

In this case we can use "Multiple float paths" function.

You can go to Tool -> Schedule -> Option -> Advanced tab ->

• Check "Calculate multiple float paths"
• Check "Free Float"
• In "Display multiple float paths ending with activity", you choose the activity you want the critical path ending with.
• In "Specify the number of paths to calculate", I usually choose "1".
