Ever struggled with a formula in DAX that does not compute what you want? It has happened to us many times, and we know that the problem is ALWAYS related to the evaluation context. Filter context, row context, and context transition, are only the starting point of a deep dive into how DAX computes the evaluation context for a formula.

See several examples of formulas that lead to unexpected results and learn the unifying theory of evaluation contexts based on filter context, row context, filter context operators, and blocking semantic. If you are serious about DAX, this session is a real must.
