Thanks for your prompt reply.
Yes my original understanding was that master project and program are
interchangable terms, once master project published to server, we call it
program.\
However, later i got confused by a paragraphy in a white paper "What is new
in project server 2007". It says " .... Using the Program Center in Project
Web Access, a program manager can create a new top-down program, assign
dates, define commitments, and even define any required custom fields. This
program can be built from scratch, or built from a previously submitted
proposal. " Looks like there is something called Program Center or Program
portal in project server, and user can build a program from top down, .. but
i am not able to find this feature. That is why i send out this question.
Appreciate if anyone can clarify this issue.
