问题
I have measure called Sales KG
in my cube and two dimensions: Groups
and Formats
.
Is there anyway to display last ones in single row?
I have this query:
select
[Measures].[Sales KG] on Columns,
[Formats].[Format_TT].[Format_TT] on Rows
from [Model]
and it's working, but when I try to follow examples from Internet and turn it into:
select
[Measures].[Sales KG] on Columns,
{ ([Formats].[Format_TT].[Format_TT]), ([Groups].[Group_Name].[Group_Name]) } on Rows
from [Model]
Everything ends with error saying that Elements, tuples and sets in functions must use same hierarchy
.
I am new to MDX. I don't know why it works for others and no work for me. 3 days ago I didn't even knew about it's existence.
回答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]
