Dax - how to subtract one pivoted matrix column from another (power bi) 0. The table is not displayed, but is used to provide input to other functions. If we had a way of defining a global table variable, we could perform the filtering of the calendar table once, and then reuse it across all of our measures, as exemplified by Scott.
