change working time

[Mocha]

Hi, im Yogi.
i would like to ask about change working time in Project Profesional 2007.
I have created Project in Project Pro then i publish.
In the next day... i open that project in project pro and i want to set my
employee working times.
I go to tools -> change working time.
but i couldn't write anything in exceptions fields. I really sure that i
have logged in as Project amnager and im sure that i have administrator
priviledge in Project server.
Then i tried to work offline. I saved my project as mpp file in local
storage. Then i open that file, i go to tools -> change working time. Now i
can read in the exceptions field.
My question is : It is necessary to create the project as Mpp file and
working offline to change woriking time?
Could someone explain this?
thank you...

It is generally preferred that Project Server questions are asked on
microsoft.public.project.server.
