When your VTS developer set up your user account, a number of user privileges or permissions were assigned to your user account. User privileges are a set of rules that define which options and specific functions of an application are available to you. These user privileges have been arranged according to your specific operational duties. Your VTS developer can explain which specific privileges you have been assigned, and how they work.
If you have not been granted the full complement of user privileges, you may encounter some features that have been disabled. Disabled features appear grayed-out, or cause an access denied message to appear when you attempt to access the feature (as shown below).

When you try to access certain features of an application for which you do not have user privileges, a message box might appear to inform you that you do not have access to that feature.
The sections that follow describe the process involved in logging on and logging off your user account.
