QUESTION:

Do you have any experience with setting up an multiproject in OPE? I have many OPE project, which I have to "put together" to multiproject file. Each of them has correctly set up start and finish date in project dates, but when i insert them into one file as external subproject and I run the time analysis with date now set to the oldest start date from all subproject all projects start dates changes to this date.

ANSWER:

After you combine the different projects into 1 master project, open the master project and for each external sub-project, add a constraint for each of the sub-project constraining the Start and Finish date. What this does is lock the start and finish date for this external sub-project.

After this you can time analyze.

The beauty of this is that you can assign access rights to the external sub-project so that others can manage these sub-projects, while at your level you can see all of the rollups at master level.
