There is a report based on MDX statement. This statement has MEMBER_KEY within DIMENSION PROPERTIES clause, so keys are retrieved. However expression =Fields!Month.Key where Month is a dimension attribute, which has a 2 columns key, always returns an empty string. I also tried =Fields!Month.Key(0) and =Fields!Month.Key(1) in my attempt to extract 2 values separately. That did not work either, returns an error. It would be ineteresting to note that this works good for attributes, which have a single column key - the correct value is returned. So how to get the values, which represent a multiple column Key?

Hi Dmitry Otblesk, As a workaround to retrieve multiple column key separately, I suggest you to get them respectively in the dataset query, like with member Measures.key1 as [Customer].[State-Province].currentmember.Properties("Key0") member Measures.key2 as [Customer].[State-Province].currentmember.Properties("Key1") select {Measures.key1,Measures.key2} on 0, [Customer].[State-Province].[State-Province] on 1 from [Adventure Works] And then, drag the fields Key0 and Key1 to corresponding tablix filed.

Yes, this really works. Thanks!
