Question

我正在尝试将某个类别及其子类别中所有产品的销售额相加，只为具有相同产品维度密钥的产品添加销售额一次。

每个类别可以包含任意数量的子类别，每个子类别可以拥有自己的任意数量的子类别，最多五个子类别。子类别的数量可以变化因此category_hierarchy中的category_dimension具有以下级别：

main_category，sub_category_1，sub_category_2，...，sub_category_5

可能看起来像这样：

id    main_category     sub_category_1    sub_category_2     sub_category_3   ...
1     Electronics
2     Electronics       Camera & Photo
3     Electronics       Camera & Photo    Accessories
4     Electronics       Camera & Photo    Digital Cameras
5     Electronics       Camera & Photo    Film Photography   Film Cameras
6     Electronics       Camera & Photo    Film Photography   Film
7     Electronics       Headphones
8     Home & Kitchen
...

在事实表中，每个类别每天都有每个产品的销售数字，每个产品可以属于多个类别（如果产品属于多个类别，则每个类别中的每个类别具有相同的销售数量），例如

id    product_id    category_id    date_id      sales   other_information
1     1             1              2016-06-30   4       AAA
2     1             2              2016-06-30   4       BBB
3     1             6              2016-06-30   4       CCC
4     2             2              2016-06-30   5       DDD
5     2             4              2016-06-30   5       EEE
...

如果我现在运行一个简单的MDX查询来显示每个类别的销售数量，如果产品属于多个类别，它会多次将销售数量相加：

SELECT 
  {[DATE_DIMENSION].[DATE_HIERARCHY].ALLMEMBERS} ON COLUMNS
 ,NON EMPTY 
      {[CATEGORY_DIMENSION].[CATEGORY_HIERARCHY].ALLMEMBERS}
    * 
      {[PRODUCT_DIMENSION].[PRODUCT_HIERARCHY].ALLMEMBERS} ON ROWS
FROM [Cube]
WHERE [MEASURES].[SALES];

我希望在2016-06-30期间始终获得产品1的销售4和产品2的销售5（但仍然能够按周/月/年汇总销售额）：

这还没有完成或测试 - 这只是最初的想法：一旦我有权访问它，我就需要对AdvWrks进行测试。

根据您的需要调整所有成员是非常复杂的。

WITH 
SET [All_tuples] AS
    ORDER(
      {[CATEGORY_DIMENSION].[CATEGORY_HIERARCHY].[CATEGORY_HIERARCHY].MEMBERS}
    * {[PRODUCT_DIMENSION].[PRODUCT_HIERARCHY].MEMBERS}
    , [PRODUCT_DIMENSION].CURRENTMEMBER.MEMBER_CAPTION
    , BDESC
    )
SET [NoDupes] AS
  FILTER(
     [All_tuples] AS X,
     X.CURRENT.ITEM(1) NOT IS X.CURRENT.LAG(1).ITEM(1)
  )
MEMBER [CATEGORY_DIMENSION].[CATEGORY_HIERARCHY].[All].[Category I NEW] AS
  AGGREGATE(
    [NoDupes]
  ) 
SELECT 
  {[Measures].[Sales]} ON COLUMNS
 ,NON EMPTY 
   [CATEGORY_DIMENSION].[CATEGORY_HIERARCHY].[All].[Category I NEW] ON ROWS
FROM [Cube];

MDX：总结，忽略名称重复
