Long answer, hope I covered what you were looking for...
If you are trying to just use PWA without MS Project 2003 (or 2002)
Professional, it won't work because MS Project is an integral part of MS
Project Server. To answer your questions specifically assuming you using MS
Project, here goes:
My answer for resource creation in PWA is "no".
--- In order for Project Server to work correctly and post all data
correctly, all resources, whether a "PWA/Project Server user" or a "Windows
authenticated user" need to be created as a resource using MS Project to add
the new resources. If you create resources directly in PWA, they will not
work properly for all functions.
My answer for task assignment or re-assignment is "yes"
--- Tasks can be created in PWA but the Project Manager for that plan needs
to approve it and update it in an exisitng MS Project plan.
--- Anyone with delegate task authority can re-assign a task; but again, the
Project Manager for that plan needs to approve it and update it in the
exsisting MS Project plan.
--- My preference is that I don't like to use either of these methods
especially id the project plan is greater than 500 lines long. It is
awefully difficult to figure out what's a good assignment/re-assignment ion
such cases and it is cleaner if such changes are communicated directly with
the PM, since she/he may have a better location to place that task, change
the wording on a task, have a better rersource, or an approved resource to
use, etc. etc. Once youget in the accept/reject cycle for changes through
PWA, it gets messy...
If that does not answer your question, please re-post!
Thanks,
