Sinister --
In the future, please post your Project Server questions in the
microsoft.public.project.server newsgroup, as this newsgroup is dedicated to
the Microsoft Project desktop application only. To answer your question,
the people who state that you should never save a master project to Project
Server are INCORRECT! It is safe to save a master project in either Project
Server 2002 or 2003, but you should NEVER PUBLISH a master project using
either of those versions, as this leads to duplicate task assignments on the
PWA timesheet page for each resource assigned to tasks in the subprojects.
In Project Server 2007, on the other hand, you can safely save AND publish a
master project without the duplication of task assignments issue. Hope this
helps.
