SSAS DRILLTHROUGH - Specified query is too complex error.

Hi Guys,

I'm working on an SSAS 2012 OLAP cube with around 100 dimensions and a single measures group. When I try to run a simple DRILLTHROUGH query such as:

DRILLTHROUGHMAXROWS 1000 SELECTFROM [Cube] WHERE ([Measures].[Fact_Count])

I get an error as below.

The specified query is too complex to be evaluated as a single statement.

Does anyone have any experience of this error and how to work around it? If I remove the majority of the dimensions from the cube I can run this query successfully. Looking at the limits set for analysis services I should be well within these.

Thanks in advance
