Hi Ashish,
You need to check Parameters in Transaction Code: SU01 . In User parameter "MOL" specifies country grouping.
For example: We use "40" for India , 10 for USA etc We have different Molga Country groupings for different countries. When you assign 40 for india then it will default when user go in to tables and programs.
User Parameter UGR indicates HR Usergroup. When you assign this parameter in SU01 to a user id, it will determine what actions the user can see in PA40 and also what infotypes the user can see in PA30 menu.
Regards
Rajesh
