尝试在MDX中计算四分位数

我的数据如下所示：

ID                                   |PersonID  |CompanyID  |DateID  |Throughput |AmountType
33F467AC-F35B-4F24-A05B-FC35CF005981 |7         |53         |200802  |3          |0
04EE0FF0-511D-48F5-AA58-7600B3A69695 |18        |4          |201309  |5          |0
AB058AA5-6228-4E7C-9469-55827A5A34C3 |25        |69         |201108  |266        |0

大约有一百万行。列名称*ID引用其他表，因此它们可以用作维度

我有一个OLAP多维数据集，其中列吞吐量作为度量，其余部分作为维度

我想计算吞吐量度量的四分之一和三分之一

我遵循了这个指南： 连同这篇文章：

从我尝试使用此MDX查询的用户中：

WITH
SET selection as ([Dates].[Year].&[2014],[Dates].[Month].&[1])  

SET [NonEmptyIds] AS
 NonEmpty(
      [ThroughputID].[ID].[id]
   *[ThroughputID].[ID].[Id].ALLMEMBERS
  ,
  {[Measures].[Throughput]} * [selection]
 )
 SET [ThroughputData] AS 
ORDER
    (    
        [NonEmptyIds],  
        [Measures].[Throughput], 
        BASC
     )
MEMBER [Measures].[RowCount] AS COUNT (ThroughputData)
MEMBER [Measures].[i25] AS ( .25 *  ( [RowCount] - 1 ) ) + 1
MEMBER [Measures].[i25Lo] AS FIX([i25])   - 1
MEMBER [Measures].[i25Rem] AS ([i25] - FIX([i25]))
MEMBER [Measures].[n25Lo] AS (ThroughputData.Item([i25Lo]), [Throughput])
MEMBER [Measures].[n25Hi] AS (ThroughputData.Item([i25Lo] + 1), [Throughput])
MEMBER [Measures].[Quartile1] AS [n25Lo] + ( [i25Rem] * ( [n25Hi] - [Throughput] ))

SELECT
selection ON 0,
[Measures].[Quartile1]
ON 1
FROM (SELECT [Dates].[Y-H-Q-M].MEMBERS ON 0 FROM [Throughput])

但是我得到了：'查询（6，7）ID层次结构在交叉连接函数中使用了不止一次。'

我是OLAP和MDX的新手。有什么问题吗？我该如何计算四分位数

我在某个地方读到，在计算四分位数时，我需要ID维度才能得到一个包含所有值而不是聚合值的集合…

罪魁祸首是以下代码：

SET [NonEmptyIds] AS
 NonEmpty(
      [ThroughputID].[ID].[id]
   *[ThroughputID].[ID].[Id].ALLMEMBERS
  ,
  {[Measures].[Throughput]} * [selection]
 )

在交叉联接中不能多次使用同一层次结构。这里您已经使用了两次

[ThroughputID].[ID]

。请尝试以下方法：

SET [NonEmptyIds] AS
 NonEmpty(
      [ThroughputID].[ID].[Id].ALLMEMBERS
  ,
  {[Measures].[Throughput]} * [selection]
 )

顺便说一句，我认为您可以简化此脚本，将子选择

从（选择[Dates].[Y-H-Q-M]。0上的成员从[Throughput]）

从[Throughput]删除为只从[Throughput]
