Another way to Drill Down in Tableau is to use the DrillDownTree Extension. The power of the DrillDownTree Extension is that it opens up many drill-through paths for your end user to choose based upon the answers that are provided, with minimal development time for the dashboard builder.
A good use case for using the DrillDownTree is ad hoc and root-cause analysis. In this case, you want to transfer from the bigger picture to a lower level to pinpoint your issue’s root cause. The Extension shows a Tree Map where you can Drill Down on a measure and drill it down on any dimension. As a result of this Tree Map, you can ask relevant questions such as ‘Why is my sales not working out in X area?’. Get to the cause of these questions, analyze what caused it, and follow up!
