Any limitations with external links

G

GUY

Good day,
I am working in a program composed of 100 sub-projects.
I want to use external links with the PROGRAM schedule.
In total, I expect to have in average 5 external links per projects all
linked to PROGRAM schedule.
This could end-up with 500 external links from 100 sub-projects all linked
to the same file.

Do MS Project 2003 can handle this case?
What about EPM 2007, will it be better or worst from a performance point of
view?

In the "Help" type "Specification" and a link will appear with all types of
useful information. The limit on subproejct insertions is 998.

The direct answer to your question is there is no limits to the number of
predecessors or successors that a task may have.

You should investigate the length of a precessors string. Since a
predecessor contains a pointer to the file name, I would test to see what
happens if the string length for one predecessor exceeds 254 characters just
to be safe.

GUY,
Just to add a little advice on top of what Jim said. Make sure you keep
the master and all subprojects together, ideally in the same directory
and folder. Also, don't save "snapshot" copies of individual files for
historical backup - it creates duplicate link structures and can lead to
corruption.

As far as how this all plays with EPM, that is a question for our sister
newsgroup, microsoft.public.project.server. This newsgroup is dedicated
to questions on the stand alone versions of Project.

Hope this helps.
