Performance issue:Show id and Description for same dimension member

Question

Hi,
I am connecting a cube to another reporting system and i need to show the id of member resulting of a query.My first thought was to use this kind of code (bellow) however when i do the same thing with many dimension (many cross join ),it slow down a lot
my query.So how can i have in the same DImension member showing a description and id ? I also have a lot of statement,so i can't have just two columns in the dimension or i will need to duplication the mdx and i could drop down the performance.
So i am trying to get as a result
Dim1 | Dim2| Dim3| Measure
1 50
32 25.2
and also be able to get
Dim1                            |   Dim2                                  |  Dim3  
                            |                Measure
NameElement1Dim1 NameElement50Dim2
NameElement32Dim3 25.2
Thanks in advance
with MEMBER [Measures].[IdElement] as 
<element>.currentmember.properties("KEY")
select
CROSSJOIN({[Measures].[IdElement]},{[METRIC].[Description].[All]}),
CROSSJOIN({[Measures].[value]},{<listmetricmdx>})
} on columns,
<pointofview>
<element_and_function>
<TimeBreakdown>
} on rows
<list_filter_clause>
) as list
where ((ElementName is null AND IdElement=0) OR (ElementName is not null))
<list_condition_metric>
but i have multiple

Hi Vincent,
In your query, you use CrossJoin in it. Crossjoin function will cause the performance issue if there are a lot of properties that need to be displayed. If you cross-join medium-sized or large-sized sets (e.g., sets that contain more than 100 items each),
you can end up with a result set that contains many thousands of items—enough to seriously impair performance. For the detail information, please see:

In your MDX query, ensure only retrieval the required data. Here are some useful links for your reference.
