Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Dear All,

First I am glad to join your network. It's good to know that any problem surely has an answer on this site.

I am working with Primavera P6 v7

I have an activity with many predecessors.

One of this predecessor is a completed activity but is still indicated as a driving one.

Other predecessors didn't start but are not indicated as driving.

I don't understand why. Any clue ?

Thank you

Arnaud,

 

Do not confuse Driving Relationship with Driving Activities.  It is the predecessor logic that is determining the early start of your activity, not just the preceding activity.  In all probability, you have out-of-sequence progress and some of the predecessors to your complete predecessors are still active.  That is what makes scheduling so interesting!  Good luck.
