MDX Ratio And All Member

Hello,

I have a calculated member that is a ratio calculation. It works fine but I would like that the value for the "All" member to be the sum of the children.

So I have the following MDX where the calculated member [Dim Group Rubric].[Group Rubric Description].[BO + ADM Cost] does not give me good results for the "All" member:


WITH

MEMBER [TOTAL YEAR CONTRACT] AS sum({[Total Year]},[Dim Contract].[Contract Number].[563131])

MEMBER [TOTAL YEAR BU] AS sum ([Total Year])

MEMBER [Dim Group Rubric].[Group Rubric Description].[TOTAL BU PVN] as

([Dim Group Rubric].[Group Rubric Description].[PVN], [TOTAL YEAR BU])

MEMBER [Dim Group Rubric].[Group Rubric Description].[TOTAL BU BO + ADM] as

([Dim Group Rubric].[Group Rubric Description].[BO + ADM], [TOTAL YEAR BU])

MEMBER [Dim Group Rubric].[Group Rubric Description].[BO + ADM Cost] as

([Dim Group Rubric].[Group Rubric Description].[PVN], [TOTAL YEAR CONTRACT])

/ ([Dim Group Rubric].[Group Rubric Description].[TOTAL BU PVN], [TOTAL YEAR BU])

* ([Dim Group Rubric].[Group Rubric Description].[TOTAL BU BO + ADM], [TOTAL YEAR BU])



SELECT

NON EMPTY {[TOTAL YEAR CONTRACT],[TOTAL YEAR BU]}

ON 0,



{[Dim Group Rubric].[Group Rubric Description].[BO + ADM Cost]}

*

UNION(

[Dim BV Organisation Finance].[Business Unit].[All]

,FILTER(

[Dim BV Organisation Finance].[Business Unit].children

,[Dim BV Organisation Finance].[Business Unit Code].currentmember.name

= '071MIND1'

)

,FILTER(

[Dim BV Organisation Finance].[Business Unit].children

,[Dim BV Organisation Finance].[Business Unit Code].currentmember.name

<> '071MIND1'

)

)

ON 1

FROM (SELECT ([Dim Year].[Year].&[2008]) ON 0

FROM (SELECT ({[Dim BV Organisation Finance].[Business Unit Code].[071MIND1]

,[Dim BV Organisation Finance].[Business Unit Code].[071DIDD1]}) ON 0

FROM [BV Contract Margin DW]))


When I launch this query I obtain:
TOTAL YEAR BU
BO + ADM Cost All - 45013 (I would like to obtain here - 90651)
BO + ADM Cost 071MIND1 - 35680
BO + ADM Cost 071DIDD1 - 54971

Please do you know what should be changed in this query to obtain the good results?

Thanks.

Guillaume
