What can you do with the "Drillthrough" feature in Power BI?

The "Drillthrough" feature in Power BI allows users to navigate from summary visuals to a more detailed report page based on specific selections made in those visuals. This feature enhances data exploration by enabling users to click on a data point in a chart, table, or any visual, which then takes them to a detailed page that provides further insights related to that selection.

For instance, if you have a sales dashboard summarizing sales by region, a user can select a particular region and drill through to a detailed page that breaks down sales figures for individual products within that region. This capability not only improves the user experience by presenting more granular data but also aids in deriving deeper insights from the original summary visuals.

The other options do not accurately represent the capabilities of the Drillthrough feature, which is distinctly aimed at enhancing navigation and detailed exploration of data. Exporting data to Excel pertains to data export functionalities, narrowing down data focuses on filtering within visuals, and changing the report layout pertains to overall design adjustments rather than drill-through navigation.
