ssas - 组合两个计算的度量并在 MDX 中使用组合结果

Question

我正在创建两个不同的计算度量，我想在来自同一个多维数据集的一个查询中使用这两个计算度量的结果。

创建的计算度量之一是 -

With Member [Measures].[VenueSalesCost]
 as
 (
 [Measures].[Amount - Reporting Currency]
)
Select [Measures].[VenueSalesCost]
 on columns
 from  [Project accounting cube]
where 
[Chart of accounts].[Main account name].&[Venue Hire Costs]

第二个是——

 With Member [Measures].[VenueSalesAmount]
as (
[Measures].[Amount - Reporting Currency]
)
 Select [Measures].[VenueSalesAmount]
 on columns
 from  [Project accounting cube]
where 
[Chart of accounts].[Main account name].&[Rental of Venue]

现在我想在我的查询中使用这两个度量。请让我知道如何结合这两个度量。

Answer 1

只需将WHERE不同查询的条件移动到计算度量的定义元组中：

With Member [Measures].[VenueSalesCost]
     as
     (
     [Chart of accounts].[Main account name].&[Venue Hire Costs],
     [Measures].[Amount - Reporting Currency]
     )
     Member [Measures].[VenueSalesAmount]
     as 
     (
     [Chart of accounts].[Main account name].&[Rental of Venue],
     [Measures].[Amount - Reporting Currency]
     )
     Member [Measures].[new Measure]
     as 
     [Measures].[VenueSalesCost] - [Measures].[VenueSalesAmount]
Select {
       [Measures].[VenueSalesCost],
       [Measures].[VenueSalesAmount],
       [Measures].[new Measure]
       }
       on columns
 from  [Project accounting cube]
