Cecilia Brusatori takes us through Power BI’s drillthrough capabilities:
The drillthrough feature in Power BI will let you let you go into more detail about a specific column in a visualization.
In the most simple way, you can enable a feature that will let you right click on a visual containing the specified column, and take you to a whole different page inside your report where you created more content to provide more details related to that same column.
