I am currently preparing a project schedule for a client. Project spec says: (1) Schedule must show critical path. (2) Critical path should be defined as the "Longest Path" (3) Last activity (Project Finish Milestone) must have a "Finish On" constraint as the deadline.
The problem I am facing is that the project is currently scheduled to finish before the deadline (30 days of float). P6 is not showing a critical path becaus of the 30 days gap between the last two activities on the schedule (End Mobilization and Project Finish Milestone). I tired changing the constraint to "Finish on or before" but client rejected it.
Client said "Longest Path" will always show critical path regardless of the 30days float. Why is my schedule not showing a critical path?
