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

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!
