How to enable Pivot Table button in Dynamics AX 4.0

I need to enable the Pivot Table button in Dynamics AX 4.0

After several test i found that i can enable the button adding the users to the Dynamics AX Admin group.

I found also that adding the users to the Administrators Windows group doesn’t work, and that adding them to a role in Analysis Services too doesn’t solve.

Apparently the users i want to grant the button have the same rights as the Admin group on the forms containing the button.

I need to enable the Pivot Table button for several users, but don’t want to add them to the Admin group.

Any idea about this?

Thanks in advance
