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.

Hi,

As far as i know, P6 does not support subprojects like P3. the question starts here.

I have to change values of resources in a massive schedule which is consisted of 14.000 activities and 55.000 resource assignments.

I can export these assignments & resources into excel. but after re-assigning the values for resources and stepping up to import process, p6 gives an error, written: `your system is out memory.’ and can not complete the import process. I divided the import files into 500 resource assigment each. But p6 gives the same error. so it became obvious that the problem is in the massive size of the schedule in p6, this has to be divided.

Sectional Schedule is consisted of two subsection (in different WBS) and if i can divide these two subsection (using their WBS) into two different project, (approximately 7000 activities in each) import process can be completed i suppose.

Note: these two subsection is linked to each other with many activities, and i don’t want to lose any link.

Do you have any advise or method that can be used for creating a subproject or anything else that can divide my schedule into two reasonable schedules?

Your help is appreciated.

Regards

Did you check for the durations of resouce assignments?
By the way: View "Projects" check if under Tab "Resources" the parameter "Drive activity dates by default" should be marked. If not, mark it and check in the view "Assignments" for each assignment.

This number of activities shouldn’t be a problem.

Did you check the maximum usage of memory in the Task-Manager? Ask you IT for the charge on you database server.

Good luck!

Thanks Dieter,

Using WBS, it was very easy. (my method was much more complicated and didn’t suceed. what i’ve learned from this , always think simple.)

And yes, i tried after i divide the project still same error.

By the way,
My PC is 2G-duo with 2GB ram.

-We use a server based p6 with 3 licences.
-Whole database is now consisted of 32.000 activities. And it will get even larger. (We plan to finish all schedules reaching total 70.000 activities.)
-We don’t use any additonal programming.
-total duration of this project is 1198 days. (i’ve actuals,project started in Aug 08 )

I think it’s time to consult IT department..

Thanks again.

To divide a project is rather easy.
You’ll create the second project. Then in the view "WBS" you can easily move WBS-nodes to the new project.

But this can’t be the reason: The quantities you indicated should easily be handled by a normal PC with 2G main with adequate virtual memory, for a stand-alone installation.

Which technical conditions has your equipment:
- Stand-alone or server?
- Size (no. of activities) of the whole database?
- Was there any additional programming - e.g. interface to SAP?
- Check the duration of your project and of your resource assignments

The error message is a technical one which was caused by errors. Even with a divided project you’ll probably run into the same situation.
