Newbie --
Yes, you can use the RBS field to control which resources can be seen by
Project Managers, Resource Managers, and Team Leads. Generally speaking,
Resource Managers can be thought of as "functional managers" who manage
resources but do not manage project. Generally speaking, Team Leads are
team members with some type of oversight responsibility. Obviously, Project
Managers manage the actual project plans in Microsoft Project Professional.
Hope this helps.
