DAX UDFs are here and as anticipated they are indeed revolutionizing the way we write DAX. Indeed together with the introduction of DAX UDFs, «the italians» presented «daxlib.org» a common repository for sharing Model-independent DAX UDFs. I’m also contributing there and I’ve seen how many commits and pull requests are going on and it’s quite amazing. All those functions, though, are –again– model-independent. Which is great, of course. But sometimes we want to make functions that are quite similar, but not quite the same. They have some dependencies on the model, but achieve the same kind of transformation. Just like calculation groups. What is to be done then? Well, we can always write a script that will customize then for us on run-time. Just like we did with calculation groups!
