Global

If there is no client or user associated with a system value, it applies to all users.

Client

A client system value applies to all users logged in using a particular client. A client-level system value takes precedence over a global-level one. You can specify the client associated with the system value using the Client field in the Category Values table.

User

A user-level system value applies to a particular user regardless o f the client that they specified on login. You can specify the user associated with the system value using the User field in the Category Values table. A user-level system value takes precedence over global and client-level system values.

Client/User

A client/user level system value allows you to assign different values to a system value for a user depending on the client the user chooses when logging in.
