Relationship tracing when debugging DAX is required especially if there is a possibility of ambiguous relationships or bidi.
I have struggled with AND in several cases. A simple example is a customer listing where you want to filter out all customers in common cities. In this example you would select the cities in one slicer and the result would be all customers doing business in the selected cities -> AND. Consequently the customer list gets shorter as you select additional cities.
Currently when you select cities the company listing gets longer as you click additional citis -> OR.
This is a priority issue for one of my clients TODAY.
Also bookmarks don't seem to do the trick!
Users are very confused about this!!!
VBA in Power BI would help us in developing, debugging and analysis enormously. For many, having the ability to examine and process result on reports would shorten and possibly simplify otherwise comples statements.
