AUTHORIZATION OBJECTS

Authorization objects are composed of a grouping of fields. The values in these fields will be used in authorization check. There can be a maximum of 10 fields defind on an authorization object.
Basically we use this authoirzation objects to check whether the user is having an authoirzation to run perticular transaction.  We assign authorization objects to a role with specific ACTVT type. For example a user is authorized only to view, other could be authorized to modify and so on.    IF your userid not attached to specific role than contact your basis team to resolve the problem by sending SU53 screen shot.

AUTHORITY-CHECK is the statement used in an ABAP Program to perform an authorization check against an authorization obect.  This statement will return sy-subrc is 0 if user has required authorization otherwise will return code will be other than Zero.  Each return code will have different meaning.
