Regardless of the settings for Project->Define Critical Activities:
(a) Total Float less than or equal to; or
(b) Longest Path,
…after a schedule calculation, P6 will mark certain activities on the ‘Driving Path’. The term ‘Driving Path’ is not defined in P6, however, upon observation of the internal database table “Task”, the field name “Driving_Path_Flag” is set to “Y” for activities that are on the longest overall path as shown below.
Changes to the Driving Path between Project updates are possible, however, in P6, those changes are difficult to determine without first assigning a Project as a baseline.

Zümmer reports these changes in Comparison Reports #22/23 – Added/Deleted Driving Path Activities. Shown Below:
