Primavera P6 V2
I have been having some issues recently in P6 where the software is remembering old dates and using these old dates to drive successors rather than the correct logic being the driver.
Basically I have some milestones linked to activites in my schedule and the milestones are being held out at a previous date despite the predecessor activities having moved to an earlier date.
For example; activity A was previously finishing on 25th May but is now finishing on 20th May but the successor milestone is still being held out on the 25th May.
I have checked the obvious solutions such as calendar assignment, no constraints, etc but the only way to correct it is to delete the activity and create a new one (at which point you have to re-assign all activity codes). It does not work just copying the existing activity and pasting as it still remembers the old dates!
Has anyone come accross this before and is there a solution or do I just need to accept it is one of P6's little quirks?
Many Thanks
Ben
Definitely an "External Early Start" or an "External Early Finish" constraint. Add the columns to your display and check.
Thanks for responses.
This is happening on just some activities, particuarly on my interface milestones between two parts of the schedule.
It is the Planned Start & Finish dates that are having the issues.
We are also finding circumstances where milestones have the asterix on the dates as you would if you had a constraint on the activity, but there is no constraint. However there did used to be a constraint on the activity.
It really is as though P6 is just remembering previous data and not updating correctly.
We are set to reboot the server tonight when everyone is logged off, maybe resetting the system might have an effect.
Thanks

Ben,
Is this happening on all activities, or just some? Just on one project, or multiple?
In addition to external relationships / constraints, it is also worth checking if you have any out-of-sequence working which may be causing the problem
Also worth confirming which date fields you are having problems with -early start/finish, late start finish, planned start/finish etc?
Cheers,

Ben,
Look for External Constraints or relationships to activities outside of your current schedule. Good luck!
Hi Ben,
Strange! you probably have a corrupted data base. If you have a back-up file, maybe it is worth deleting the file and restoring the back-up one.
Good Luck!
