筛选器mdx查询结果

Question

我有一个MDX查询返回如下结果：

Customer |存储|销售

A | Store_1 | 123.45

A | Store_2 | 234.56

B | Store_2 | 345.67

B | Store_3 | 456.78

C | Store_1 | 543.21

C | Store_3 | 654.32

如何查询应该有结果，显示每个客户只有一排只有第一家店：

A | Store_1 | 123.45

B | Store_2 | 345.67

C | Store_1 | 543.21

更新： 实际查询

SELECT 

    [Measures].[Sales] ON COLUMNS, 

    NON EMPTY(
    [Customers].[User].[User], [Stores].[Store].[Store] 
) ON ROWS 

FROM SALES 

Answer 1

如果我运行此：

SELECT 
    [Measures].[Internet Sales Amount] ON 0 
, 
    [Product].[Category].[Category] 
    * 
    [Customer].[Customer Geography].[Country] ON 1 
FROM [Adventure Works]; 

我得到如下：

如果我只想first为每个类别我需要做的是这样的：

WITH 
    SET [cats] AS 
    [Product].[Category].[Category] 
    SET [cats_country] AS 
    Generate 
    (
     [cats] AS S 
    , 
     S.Current 
     * 
     Head(NonEmpty([Customer].[Customer Geography].[Country],S.Current)) 
    ) 
SELECT 
    [Measures].[Internet Sales Amount] ON 0 
,[cats_country] ON 1 
FROM [Adventure Works]; 

结果在此：
