BO4.1 User rights : Hide element in Web intelligence Application

Hi all,

I'm currently setting up Access levels on BI4.1 SP5 plateform and I would like to hide some elements Web intelligence :

- Left pane : Web Service Publisher

- While creating a new report, hide others sources than Universe : Hide : Excel, BEx, Analysis View.

Is that possible ? I can't find the right access level to do that.

Thank for your answers.
