What is the maximum number of activity in P3?

Hello Albert,

As far as I know, the Limit rows of P3.1 is 32,000 & these are the activities that can be shown. However, you can add more.

The best thing to do is to create Project group if your activities are more than 32,000 or less.

For the Open Ends, for me the allowable is only Two. The Start of the Project or NTP (has no Predecessor) and the Finish, whatever activity name is it (has no Successor).

HTH.

Arnold

Thanks a lot Arnold

I had a 200,000 or so activity schedule that I converted from Microsoft Project to P3 for a Telcom project in Malaysia a few years ago. I seem to recall it ended up about 170,000 in P3.

It seemed to schedule OK but I did not update it!

Paul,

do you still need to update it? i’m in kuala lumpur right now, maybe i can use most of my spare time, instead of reading some unuseful posts in PP?

but why such a huge schedule? (if you just don’t mind answering)

There were about 700 or so mobile phone towers each with 200 activities each plus design and procurement activities. It all soon adds up.

I came across an organisation use P3 3.1 to manage like a enterprise system and the company entire projects are loaded in only one project.

Each home is around 200 activities and each year they build around 2000 of it and they keep the record I think 6 months

I believe they have something in around 500,000 activities

I have a schedule of around 50,000 for an Air Separation Unit (Pearl GTL/Qatar).
And I keep it up to date. :S

the schedule is divided into subprojects.
most of the data is updated through a couple databases I have set up.

Obviously some things need to be updated manually and always will have to.

Regards.

The real ‘limit’ for P3 is not in the number of activities but in the number of people logged-in at the same time. You should try to never have more than three people using the same P3 schedule at the same time. Above that number; you will start seeing Btrieve database corruption problems. I believe that this was the main motivating force behind Primavera switching over to the database server-base system used by P6.

We did 60,000 ++ activites using P3 for rail project
