There are two problems with this schema: 1. The schema needs a name. Otherwise, it cannot be loaded by the schema editor, e.g., <Schema name="FoodMart"> 2. 'Store Costs' is used in the CalculatedMember, but not defined as a measure. So, add: <Measure name="Store Cost" column="store_cost" aggregator="sum" formatString="#,###.00"/> And after the above changes, the query suggested by Sebastian can be run. If you want to fix the original query, change the ‘descendants’ to ‘children’, i.e., SELECT {[Measures].[unit Sales], [Measures].[store Sales]} ON COLUMNS, {[Time].[1997].[Q1].children} ON ROWS FROM [sales] WHERE [Gender].[F]
