I have been running PowerView in SharePoint 2013 for several days and very impressed with the visualizations and easy of getting to tabular data. Of course it is far less flexible than SSRS but that's the cost of simplicity. I am trying to find a forum for PowerView discussions. I don't see it here, but this is the closest I can find, does anyone know some good resources. The specific questions I have is how to put an expression in a filter. I don't see how to do that but without it I don't know how you would do "last 12 month" type reports. Also I want to know how to put the report run date on the report. The lack of expressions seems to be a killer, but it looks like a tool with a lot of potential.
