A nice feature in SAP Lumira is the ability to create custom hierarchies which allow you to drill down in an application.

In the visualization room you can select Create a custom hierarchy (but not with the geo-enriched dimensions)

I am using the 2012 Olympic data and want to drill down by Sport, Country & Athlete

You can select the hierarchy in the dimensions of the visualization

You can rename an existing hierarchy but you cannot edit a hierarchy; it would be nice to edit an existing hierarchy to add or remove elements.  (You can vote on ideas in Idea Place to support this).

Here is the visualization on Lumira Cloud

Click the Explore icon to drill down the hierarchy

I select Beach Volleyball and Drill Down to Country

Now you can see the countries who won gold and silver for beach volleyball.

I hope to learn more at BI 2015.
