To get a full list of measures in your cube, open a MDX query against your Analysis Services multi dimensional database and run the following query. The output is pretty cool, you get the measure name, measure unique name as referenced in MDX queries, measure group name and format string. Very useful for producing business documentation for the kind people using the cube… Though if you haven’t specified custom captions for your measures, you may want to export the output to Excel then add some metadata to the measure names.
