Get the latest data for each country
The traffic data is now filtered following the business rules. It still contains the data for all the available years per country. You are only interested in the latest traffic data.
You know a simple way to get what you want. First, you group the data using the three-letter country code. Since the data is already sorted descending by year, you can get the first row of each group to get the latest available traffic data for each country. Nifty!

- The
Get latest data by countrykeyword communicates the intent of the code by using clear naming. - The
Group Table By Columnkeyword handles the grouping by country. - The
Pop Table Rowkeyword gets the first row of a table. - This
RPA.Tableslibrary feels quite helpful indeed!
