MDX：Top X由两个分组和Top Y（X> Y）组成两组

Question

我想写一个查询，显示TOP 4 Internet销售额根据年和产品。并且，与此同时，我试图显示TOP 1经销商销售额根据年仅。

Year  Product   Internet Sales Amount  Reseller Sales Amount 
CY 2015 Road-150 Red, 48  $153,215      $25,021 
CY 2015 Road-150 Red, 68  $101,215      $25,021 
CY 2015 Road-150 Red, 22   $93,215      $25,021 
CY 2015 Road-250 Red, 52   $90,215      $25,021 
CY 2014 Road-150 Red, 100  $202,215      $60,021 
CY 2014 Road-220 Black, 90  $180,101      $60,021 
CY 2014 Road-65 Blue, 28  $139,465      $60,021 
CY 2014 Road-86 Red, 33   $100,001      $60,021 

我写了下面的查询，实现4强Internet销售金额按年及产品，但无法弄清楚如何将一个小节添加到结果集。

WITH 
    SET [TopSalesbyYearAndProd] AS 
    Generate 
    (
     [Date].[Calendar Year].[Calendar Year].MEMBERS 
    ,TopCount 
     (
      [Date].[Calendar Year].CurrentMember 
     * 
      [Product].[Product].[Product].MEMBERS 
     ,4 
     ,[Measures].[Internet Sales Amount] 
    ) 
    ) 
SELECT 
    {[Measures].[Internet Sales Amount]} ON 0 
,NON EMPTY 
    {[TopSalesbyYearAndProd]} ON 1 
FROM [Adventure Works]; 

Answer 1

这似乎是工作 - 有可能是一个更优雅的方式，但我还没有找到它：

WITH 
    SET [TopSalesbyYearAndProd] AS 
    Generate 
    (
     [Date].[Calendar Year].[Calendar Year].MEMBERS 
    ,TopCount 
     (
      [Date].[Calendar Year].CurrentMember 
     * 
      [Product].[Product].[Product].MEMBERS 
     ,4 
     ,[Measures].[Internet Sales Amount] 
    ) 
    ) 
    MEMBER [Measures].[TopResellerAmount] AS 
    (
     Generate 
     (
     {[Date].[Calendar Year].CurrentMember} 
     ,TopCount 
     (
      [Date].[Calendar Year].CurrentMember 
      * 
      [Product].[Product].[Product].MEMBERS 
     ,1 
     ,[Measures].[Reseller Sales Amount] 
     ) 
    ).Item(0).Item(1) 
    ,[Measures].[Reseller Sales Amount] 
    ) 
SELECT 
    { 
    [Measures].[Internet Sales Amount] 
    ,[Measures].[TopResellerAmount] 
    } ON 0 
,NON EMPTY 
    {[TopSalesbyYearAndProd]} ON 1 
FROM [Adventure Works];
