Storage Location Authorization Object on SAP

Case:
I am trying to restrict a user on some particular Storage Locations , but when we apply the restriction , the user can still access all other St Loc.. Could u pls help..

A:
Go to SPRO > MM > Inventory Management and Physical Inventory > Authorization Management > Authorization Check for Storage Locations > Here activate the authorization for storage location under plant

And use authorization object as "M_MSEG_LGO"

Note: - In this step, you activate storage location authorization for individual storage locations.
Storage location authorization means that a user has to have authorization for authorization object M_MSEG_LGO in order to enter a goods movement in the storage location, using a particular movement type. In the list of material documents, only the document items for which the user has a display authorization are displayed.


Q:
its still not restricting on any Reports. Could u pls help on the issue..
A:
Each user has user roles.
Can be seen in SU01.
The roles can be maintained in PFCG.

In PFCG you define which authorization the user gets assigned.
Dependend on transaction you assign to a user autorisation objects are defaulted. (authorization objects per transaction be seen in SU24).
