Restricting Access to the Certain Reporting Components

Hello Gurus!

I would like to restrict the user's access to the following:

1.) The INFORMATION Tab on the Bex Ad Hoc Query

2.) The INFORMATION BROADCASTING Tab

3.) The Exceptions and Conditions Button

4.) The Export To CSV Button

Is that even possible? If it is possible, can some kind soul out there be good enough to tell me how to do this please?

Thank you very much,

Philips
