In the latest release of Tableau Prep Builder (2020.1.3), we’ve added support for level of detail (LOD) calculations to make working with aggregations much easier. We’re also delighted to introduce rank and row number functions, providing even more ways to clean and reshape your data.

In the example in this post, Anton explains how to configure Prep Builder to run Python scripts and show some of the cool ways to take advantage of new support for custom Python and R script execution from within Tableau Prep flows.
