Chris Webb goes looking for unused objects:
A few weeks ago I wrote about how Semantic Link Labs now has tools with interactive UIs and showed how you could use this to view lineage and so Vertipaq-Analyzer-stuff in a notebook. I didn’t show what I think is the coolest new feature though: the ability to find the tables, columns and measures in a semantic model that aren’t used and which therefore could be deleted. There are tons of excellent third-party tools that do this available already of course but the advantage of using Semantic Link Labs for this is that you can automate the process of finding unused columns and run it from a notebook and, crucially, you have two ways of finding those unused columns: from analysing the structure of downstream reports and from analysing DAX queries captured in Workspace Monitoring.
Read on to see how it works.
