DAX : Ranking the Stars with RankX
I have to work on a ranking problem and therefore I decided to study the RANKX() function in DAX a bit further. The idea is that the RANKX function determines the rank of a certain item in a complete list of items.
I've used a blogpost of Rob Collie (RANKX-apalooza: Within and Across Groups, With Filters, Etc.) as a source for this blogpost.
