How to display multiple dimensions on rows in MDX query?

Question

I have measure called Sales KG in my cube and two dimensions: Groups and Formats.

Is there anyway to display last ones in single r

Answer 1

It is giving you the above error because you are breaking dimensionality and hierarchility. When you write

 { ([Formats].[Format_TT].[Format_TT]),
 ([Groups].[Group_Name].[Group_Name]) }

MDX translates that you have a set (marked by {}), containing two tuples ([Formats].[Format_TT].[Format_TT]),([Groups].[Group_Name].[Group_Name]), marked by "()" each. Now the issue is all the tuple in a SET must contain then same hierarchies(The principle of hierarchility), plus they should be in the same order (Dimensionality)

select
[Measures].[Sales KG] on Columns,
{ ([Formats].[Format_TT].[Format_TT], [Groups].[Group_Name].[Group_Name]) } on Rows
from [Model]
