I have made a PowerView report in which I have shown data for all regions (for instance, East, West, Central). I have created a cube role so that User can only see data for region 'Central'. I have also enabled the EffectiveUserName" property in Excel Services in SharePoint.
When User opens the PowerView report, he is able to see all the regions. Can I secure my PowerView report? If yes, then what steps would I need to take?
