Apparently, there is no easy way to export data from PowerView to Excel. Even in Excel 2013, the behavior that I would need was to have slicers shared between PowerPivot and PowerView; applying one slicer, the same would be reflected between PowerPivot and PowerView.
PowerView users will be able to view, analyse and filter the report. If they need more detailed information or data lists, they will be able to export that data to Excel. For instance, if we are making an analyse about products sold by year and countries in PowerView, I would like to be able to export that info to Excel and manipulate (add calculations, etc.) or print the data.
