Hello,
I have a schedule with a non-critical but resource-overallocated path through tasks A-B; and a critical path through task C, which is not resource-loaded. When I level the schedule, the path, including tasks A-B, becomes critical, and the path through task C becomes non-critical. This demonstrates that the A-B path is a resource-critical path.
But when I reset the schedule (resetting the critical path to go through C), select the last task in the schedule and choose
View | Activity Critical Path | Show Resource Critical Paths
The path through C appears, not the path through A-B. Again, Path C has no resources, while Path A-C has resource overallocation, which makes it critical when leveled.
So the output of 'Show Resource Critical Paths' appear to be incorrect.
The help explains the 'Show Resource Critical Paths' as follows:
Click 'Show Resource Critical Paths' to show the most critical path behind to the selected activity, and any activities whose resource assignments are contributing to the criticality of the selected activity (even if those activities are not on the activity-driven critical path to the selected activity).
I understand that P6 Professional View | Activity Critical Path | Show Resource Critical Paths tool should be able to specify that path through A-B is the true resource critical path prior to leveling.
So the 'Show Resource Critical Paths' always gives the same result as 'Show Backward Activity Paths.'
Your thoughts on the Show Resource Critical Paths tool would be appreciated.
Could this be a bug?
I have tried to implement the 'Show Resource Critical Paths' using the duration types Fixed Units/Time, Fixed Units, and Fixed Duration and Units/Time, but I always get the same results.
I am using P6 Professional r24.12.
Any thoughts or input?

I think this is a bug
Once I turn on View Activity Critical Path tool bar and use it I can not toggel it off I have to totally exit P6
When the project was levelled it is necessary to know new activity floats, what activities are critical in the current schedule, activity drags and other data that we use in the schedule that was not levelled. You can always compare what happened after leveling with the schedule before leveling and analyze changes.
But there is a problem with P6 - in many cases it calculates wrong resource constrained activity floats. Floats shown in the levelled schedule can be wrong and so be careful.
I find this feature in P6 about as useful as a shamen and a bag of chicken bones.

Thank you for your response.
If the Resource Critical Path is determined after leveling, what value does the Show Resource Critical Paths tool add? I understand its purpose is to show hidden critical paths that are hidden until you execute Show Resource Critical Paths.
I found that after leveling, I get the same outcome whether I perform either:
1) View | Activity Critical Path | Show Backward Activity Critical Paths
2) View | Activity Critical Path | Show Resource Critical Paths
Both tools list the path through A-B as the Critical and Resource-Critical Path.
Before leveling, the outcomes for tools (1 and 2) list the path through C as both the Critical and Resource-Critical Path.
I keep getting the same results for both the Backward Activity Critical Path and the Resource Critical Path. Before leveling both output paths through C and after leveling both output paths through A-B.
Can you provide an example of where (after leveling) I would get different results when performing a 1—Show Backward Activity Critical Path and 2—Show Resource Critical Path?
Any thoughts?

Resource Critical Path can be determined not before but after project resource levelling.
