I have a Project which has multiple Contract Dates (Contract Duration, 7 Contract Sections and 2 Key Dates).
As part of the Works I also have mixed working calendars (some activities run on 7-day per week calendar, but the majority are 5-day per week).
To generate a Critical Path for meeting each Contract Date I’ve used “Finish On or Before” Constraint on the Planned Completion of meeting each Contract Date (rightly or wrongly).
However, where a 7-day working activity finishes on the last day of the normal working week (or on the Saturday or within a longer non-working period) this introduces Float and by rules of P6, ends the critical path.
I'm aware that I could set the criticality rule to be less than 2-days Float (rather than the current 0), this would bring most activities back into P6’s Critical Path, however there are some activities where the 7-day working activity finishes through a 2-week non-working period. To stop this from ending the P6 Critical Path I’d have to set the criticality rule to be less than 2-weeks Float – however this would bring a hole list of other activities, that normally would not be on the Critical Path as they have up to 2-weeks Float. I've tried a few of the other options for "Compute Total Float as" and "Calendar for scheduling Relationship Lag", but couldn't get it to work (but may not have tried all possible combinations with some other settings!).
It seems that what I need to do is to filter longest Path to a specific activity (the specific activting being the selected Planned Completion activity)?
Is there a workaround / built in P6 function?
Thanks in advance.
Below are the current Schedule settngs:
