There is issues calculation median with DAX. Is it possible to calculate the Median using Excel , part of a PivotTable in a way that would work with drill down. Is it possible for Excel to retrieve the raw Mortgage Amount from Analysis Services (150 million rows or so) and calculate the median at the front end somehow.
I looked into link below but that does not seem to calculate the median on the raw data.
