Ever struggled with a formula in DAX that does not compute what you want? It happened to us many times, and we know that the problem is always (really: ALWAYS) related to the evaluation context. Filter context, row context, and context transition, are only the starting point of a deep dive in how DAX computes the evaluation context for a formula.
During the session, you will see several examples of formulas that lead to unexpected results and then you will learn the unifying theory of evaluation contexts based on expanded tables, filter context operators and blocking semantic. If you are serious about DAX, this session is a real must.
