KB3033456 - FIX: Poor performance when you run an MDX query that contains a sub-select of different granularities in SSAS 2012

Applies to: SQL Server 2012 Analysis ServicesSQL Server 2014 Business Intelligence


Assume that you are using Microsoft SQL Server 2012 Analysis Service (SSAS 2012) or SQL Server 2014 Analysis Service (SSAS 2014). When you run a Multidimensional Expressions (MDX) query against a large database that has a sub-select of different granularities, the query may take a much longer time than the single granularity under the same logic.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
