I have some dynamic filters in DAX. They are implemented with disconnected tables and the DAX code then calculates the measure based on the value selected. One thing I do to increase maintainability is to put the logic in a hidden measure. This hidden measure returns 1 or blank(). Then I multiply another measure by this, which gives the correct value. Since I have usually have over 100 measures in a cube, this makes it much easier to maintain if some of the logic were to change. Would this have any negative performance impacts?
Thanks.
