MDX;获得除了名称之外的所有值的度量集合度量

Question

此元组得到尺寸为[MyHierarchy].[MyHierarchy].&[some_value]的度量X的集合。

([Measures].[X], [MyHierarchy].[MyHierarchy].&[some_value]) 

但什么是补体 - 即Measures.X在同一层次，但不包括[MyHierarchy].[MyHierarchy].&[some_value]

我敢肯定它的EXCEPT功能，但我似乎无法得到正确的语法。

Answer 1

的总体思路，以任何一种集聚集了是一样的东西：

with member [Measures].[Y] as 
     aggregate( 
     except([hierarchy].members, { excluded }), 
     [Measures].[X]) 
     ) 

骨料（）正在处理[措施]的任何实际的聚合。问题是，如果[层次结构] .members包含一些中间（父）成员，则会计算两次值。

如果聚集SUM和你已经一个所有成员，则给出预期的结果如下：

with member [Measures].[Y] as 
     ([hierarchy].[all], [Measures].[X]) 
     - sum({ excluded }, [Measures].[X]) 

如果没有所有那么你可以使用第一级成员：

with member [Measures].[Y] as 
     sum([hierarchy].levels(0), [Measures].[X]) 
     - sum({ excluded }, [Measures].[X])

Answer 2

以下expresion可与非线性aggrega重刑功能：

WITH MEMBER [Measures].[Y] as 
     Aggregate( 
     Except([MyHierarchy].[MyHierarchy].&[some_value].Level.Members, { [MyHierarchy].[MyHierarchy].&[some_value] }), 
     [Measures].[X]) 
     ) 

你可以概括它时，你必须排除一些成员属于同一级别（排除的成员都在excludedMembers集）：

WITH MEMBER [Measures].[Y] as 
     Aggregate( 
     Except(excludedMembers.Item(0).Level.Members , excludedMembers), 
     [Measures].[X]) 
     )
