The System Management and Help Desk facilities which you are permitted to use are determined by the security code allocated to each facility, and the privilege (or authorization) level which has been assigned to you. You may use only those facilities for which the security code is equal to, or less than, their privilege level.
Note: If security codes have been set for individual components of a facility then some parts of the facility might be restricted.
By using the security codes and privilege levels appropriately, several facility 'groups' may be set up, each group accessible by only certain users.
