Authorization Group in se38

Hi everybody,

what is the use of Authorization group in se38 attribute? can we create and assign our own one?

The actual scenerio which i am facing here is My report should not be viewed by some grop of users. My friend is saying i can do that through the above said one. But i know i can do that using AUTHORITY-CHEK. What i am asking here is can i accomplish this task by the above said attributes.

Points will be awarded.

Thanx in advance.
