The Roles and Features home page shows you the number of installed roles and features in a table on the left-hand side. Once a role or feature is selected, the table on the right-hand side displays a list of computers with that role or feature installed.
From the Roles and Features home page, you can drillthrough to the Computer Role and Feature Details page for additional information.
Once a filter is selected, for example, the Collection Name, it remains in place until replaced by another filter. Filters are generally enabled when you drillthrough from one page to another page. In the footer of all pages, you’ll see, Date Last Refreshed. This information tells you when the Roles and Features data was last queried and imported from SCCM into Power BI.
