Hello there,  yes, a third part of the snapshot report and I’m not even sure it’s the last one. The thing is that since the last post there has been some major improvements on the set up that I thought are worth sharing. In my previous post I ended up with a small defeat. There were some combinations of filters that when I drilled through to see all the historic records of those order IDs I would not get any rows. Also my set up included duplicating the fact table which is a big no-no in most use cases and a shameful solution from a modeler perspective. Even though this was the best I had, I decided to present the topic on two events, one was the Data Community Day Austria 2023 and the other was @PowerBIEspanol Virtual Conf 2023 (Fin Tour Power BI Days), just a few days apart. The fact that I had to present the solution to a lot of people kept me thinking and looking for solutions, so with the help of the always reliable Ricardo Rincón I finally found out a working solution just duplicating dimension tables and creating dimension tables for everything (even comments and stuff like that). That was much better but not quite scalable. In real life things are ugly and tables have many columns. So while fighting with the same use case at work, I found a sneakier and much better solution that got rid of all those superfluous dimension tables reducing the need of them to just 2. While preparing the presentations I also worked a bit on the report layer and I’ll also share some techniques I came up with that can be helpful at some point. But enough of all this talking, let’s do what? Let’s get to it.
