If using the software resource leveling most software longest path and float calculations will be unreliable. P6 calculation of float and longest path break under resource constraints as documented by Oracle and many others. [5][6]

[5] P6 -What are critical path activities?

[6] “Longest Path Value” – TomsBlog

If some relevant constraints such as constraints on renewable resources, consumable resources, spatial resources and conditional logic is missing then the schedule is not reliable. Missing a single schedule constraint might render the schedule not feasible.

Thank you
