Using Power BI Dynamic M Parameters In DAX Queries

As I’m sure you’ve guessed by now I’m a big fan of dynamic M parameters in Power BI. They’re easy to use in Power BI Desktop but what if you want to use them in your own DAX queries?

Power BI Report Performance And The Number Of Visuals On A Page

When you’re faced with a slow Power BI report it’s very easy to assume that the problem is something to do with the dataset, how it’s modelled and how the DAX has been written, and then disappear down a rabbit hole of Marco-and-Alberto videos trying to shave milliseconds of the time taken by each DAX query the report runs.
