Assigning Authorization to a User 
Before an authorization for an activity can be checked, it has to be assigned to one or more users.
You have authorizations for authorization object S_RSEC. You have already created or generated an authorization.
You have two options for assigning an authorization to a user:
1. In the SAP Easy Access menu, choose Business Explorer ® Management of Analysis Authorizations.
2. On the User tab page, choose Analysis Authorizations ® Assignment.
3.
Select an
iView and choose
Edit.
4. You have two options:
¡ Under Authorization Selections, choose one or more previously created authorizations. With Insert you can add the authorization to the list of assigned authorizations.
¡
With
Node, can select nodes for a hierarchy that
you created previously for the characteristic 0TCTAUTH in hierarchy
maintenance. The authorizations are available as virtual master data for the
characteristic 0TCTAUTH and can be grouped hierarchically in order to create
thematic arrangements.

The authorizations that were just inserted are marked. This allows you to undo incorrect entries immediately.
5. Save your entries.
The analysis authorizations can be (but do not have to be) assigned by roles. To assign an authorization to a user, it is sufficient to proceed as described above.
As an alternative, authorizations can also be assigned using profiles for the authorization object S_RS_AUTH, the entries of which are analysis authorization names. In this way, you can assign authorizations to a user using roles as well using the general role maintenance and the general user maintenance for SAP NetWeaver.
The input help in the role maintenance for this authorization object provides all existing, defined BI analysis authorizations.
Mixed scenarios, which mean assignments from roles in addition to the directly assigned authorizations, are also possible.
An authorization for all values of all authorization-relevant characteristics is created automatically in the system. It has the name 0BI_ALL. It can be viewed, but not changed. Every user that receives this authorization can access all the data at any time. Each time an InfoObject is activated and the property authorization relevant is changed for the characteristic or a navigation attribute, 0BI_ALL is changed. A user that has a profile with the authorization object S_RS_AUTH and has entered 0BI_ALL there (or has included it, for example with the pattern *) has complete access to all data.

This authorization is the simplest way for you to assign authorization for everything. It does make sense to change standard profiles for specific user groups.
On the Manual/Generated tab page, you see the manually created and generate authorizations in this transaction for this user. They are differentiated with icons.
On the From Roles/Profiles tab page, the authorizations for this user that originate from roles are displayed. They cannot be changed here. You can create this type of authorization in role maintenance.
