Debugging DAX Measures in Power BI

Marco Russo and Alberto Ferrari bust out the oscilloscope:

Finding errors in DAX measures has always been difficult because a single DAX measure produces different results in different cells of the same report, and we do not have a direct way of executing the code step by step in Power BI. This article describes four techniques to find an error in a DAX formula: we start with variable manipulation that does not require any external tool, and then we see how to leverage features available in DAX Studio, DAX Debug Output, and Tabular Editor 3.

Do check this out, especially if you spend a lot of time writing DAX code.
