Hi:
Much of the data in an R/3 system has to be protected so that unauthorized users cannot access it. Therefore the appropriate authorization is required before a user can carry out certain actions in the system. When you log on to the R/3 system, the system checks in the user master record to see which transactions you are authorized to use. An authorization check is implemented for every sensitive transaction.
You can check Authority object with the ABAP stament
AUTHORITY-CHECK OBJECT auth_obj [FOR USER user]
ID id {FIELD val1}|DUMMY
With this parameters:
The AUTH_OBJ parameter specifies the authorization object.
The ID parameter specifies an authorization field (in the authorization object).
The FIELD parameter specifies a value for the authorization field.
