How to find all tables and views used in a SQL Server Analysis services cube?

Someone asked me today if there is an easy way to find all tables, views used in a SSAS cube. You can always see XMLA file to find the tables or check the data source view in the cube definition. But we have some cube databases which have more than 100 tables and going through XMLA or DSV is time consuming.

Good thing is Microsoft provides DMVs explore metadata of a cube database. Here is a sample query to get meta data for a cube

1. Connect to the SSAS instance via SSMS.
2. Open new MDX query
3. Copy paste the query below
   SELECT * FROM $SYSTEM.MDSCHEMA_DIMENSIONS
   
   WHERE CUBE_NAME = 'cube_name'AND DIMENSION_NAME <> 'Measures'

4. Change the cube name and execute the query
