Time Intelligence in DAX
Time Intelligence is probably the most interesting feature of any analytical solution. Computing Year To Date, Month To Date, Same Period Previous Year is quite easy in DAX but, as soon as the customer requests for time intelligence require working days evaluation, complex and custom calendar shapes, seasonal pattern recognition, the DAX formulas start to be harder to write.
In this session we are going to show how to compute classical time intelligence with the built-in DAX functions. Then, we will show some more complex time intelligence formulas that require to think out of the box, using advanced data modeling and querying techniques to produce interesting and useful formulas.
