MDX adding together two cube measures across two role playing dimensions

Question

I have two queries which I would like to join together,which would give me the calculated total of the row. The problem I have is that although the measures are from 1 fact table the Squad names are in two role playing dimensions. I'm extremely new to MDX.

The outcome would be something like

 | Competition    | Squad   | Goals A | Goals B | Total (Goals A + Goals B)|
 |----------------|---------|---------|---------|--------------------------|
 | Premier League | Arsenal | 25      | 15      | 40                       |

Thanks in advance.

Query1:

SELECT 
([Measures].[Goals A]) ON COLUMNS,
NON EMPTY ([Dim Competition].[Hierarchy].[Competition ID],[Squad A].[Squad Name].ALLMEMBERS) ON ROWS
FROM 
[FDC Star]
WHERE [Dim Competition].[Competition ID].&[1];

Query1 result:

Competition     Squad                 Goals A

Answer 1

After spending many hours trying to come up with a solution I have finally solved my query.

Thanks

    WITH  
    MEMBER [Measures].[GFA] AS 
    (
    ([Measures].[Goals A]),
    linkmember([Dim Squad].[Squad Name],[Squad A].[Squad Name]),
    root([Squad Name])
    )
    MEMBER [Measures].[GFB] AS 
    (
    ([Measures].[Goals B]),
    linkmember([Dim Squad].[Squad Name],[Squad B].[Squad Name]),
    root([Squad Name])
    )
    MEMBER [MEASURES].[GF] AS
    (
        [Measures].[GFA] + [Measures].[GFB]
    )
    select 
    {[Measures].[GFA],[Measures].[GFB],[MEASURES].[GF]} on 0,
    non empty [Dim Squad].[Squad Name].allmembers on 1
    from [FDC Star]
    where [Dim Competition].[Competition ID].&[1]

Answer 2

You can try something like this:

WITH MEMBER [Measures].[Goals B Linked]
AS (LinkMember([Squad A].[Squad Name].CurrentMember, [Squad B].[Squad Name]), [Measures].[Goals B]),
MEMBER [Measures].[Total]
AS [Measures].[Goals A] + [Measures].[Goals B Linked]

SELECT 
{[Measures].[Goals A], [Measures].[Goals B Linked], [Measures].[Total]}  ON COLUMNS,
NON EMPTY ([Dim Competition].[Hierarchy].[Competition ID],[Squad A].[Squad Name].ALLMEMBERS) ON ROWS
FROM 
[FDC Star]
WHERE [Dim Competition].[Competition ID].&[1];
