Slicer visuals can serve as an alternative to distinct or dedicated report pages. With a slicer, a user has the flexibility to select one or multiple values on the same report page, such as Northeast and Southwest, without needing to navigate to a dedicated page. Additionally, by consolidating dedicated report pages, slicers can simplify report development and management.
However, dedicated report pages are valuable for supporting email subscriptions, data alerts, and dashboard visuals specific to a particular value such as a sales region. In the following image from the Power BI service, an email subscription can be set to any of the report pages within the USA SALES AND MARGIN report:
As one example, the visuals from the Northeast report page could potentially be pinned to a Northeast dashboard (or other dashboard) and used in data alerts and notifications for the Northeast team as well. These region-specific capabilities are made possible by the distinct report pages of visuals filtered for the given sales territory region.
