Assigning a Primary Responsibility
Each user can have multiple responsibilities assigned, in order to provide access to all necessary views. One responsibility is defined as the primary responsibility. The user sees the tab layout associated with his or her primary responsibility. The Site Map provides this user with access to the superset of screens and views defined in the responsibilities with which the user is associated.
The administrator sets the primary responsibility for a user by checking the Primary flag in the Responsibilities dialog box, in the Administration - User screen.
NOTE: By default, the first responsibility assigned to a user (based on timestamp) becomes the primary responsibility. Particularly for customers who are upgrading, the administrator should verify that the correct primary responsibility is assigned to each user, or specify the desired primary responsibility.
