In this webinar, Mitchell covers Filter Context, DAX functions and options for dealing with confusing totals. This information cannot be derived from filter context alone. Understanding context and using context effectively are critical for building high-performing, dynamic analyses, and for troubleshooting problems in formulas. Best regards!

The filtering functions let you manipulate data context … Not change with filters or slicers in the report visual. For Power BI DAX Measures, one of the hardest concepts to grasp is the Filter Context.

Controlling the context means controlling interaction of … The state below shows the DirectQuery compatibility of the DAX function. It returns all the values from the column (s) or all the rows from the table, ignoring any existing filter context. The filter and value functions in Data Analysis Expressions (DAX) are some of the most complex and powerful, and differ greatly from Excel functions. They both work on the result of a formula, but in different ways. I'm working in SSAS Tabular, not PowerPivot. Now it is possible to perform a calculation with interaction between multiple columns.
