SAP BW Authorizations in AfO

Hello,

Currently we have given authorization to the Infoprovider in one role and then we restrict the data in Analysis Authorization to certain regions for some users.

The problem is:

In BEx queries we have in rows/columns/filters the infoobjects that are authotization relevant - here we have no problem.

The problem start when the user in AfO open the Composite Provider directly (in Search and Area tab).

Data is agregated and the user can see all the keyfigures for the whole world and also drilldown for certain objects.

Question:

Is there a way to restrict users to not open the composite providers directly in AfO and use only the queries?

Thanks in advance.
