如何覆盖 SSAS 商业智能“货币转换”用于责任计算

Question

我正在 Analysis Services 中设置一个新的多维数据集，并使用商业智能向导来解决货币转换问题。现在这一切都很完美，货币在叶级别进行转换并汇总以显示在用户选择的报告货币中。

我现在的问题是责任的计算。对于责任，我需要总结每种货币的金额，然后使用最新的“日终汇率”进行转换。我将“日终汇率”作为 LastNonEmpty 度量，但我不知道如何避免叶级转换，如下所示：

// This is the Many to One section  
// All currency conversion formulas are calculated for the pivot currency and at leaf of the time dimension 
Scope ({ Measures.[Money] } ); 
  Scope( Leaves([Date]) ,[Reporting Currency].[GBP], Leaves([Currency])); 

    // Convert Local value into Pivot currency for selected Measures that must be         converted with Measure rate [End Of Day Rate] 
        Scope( { Measures.[Money] } )
            This = [Reporting Currency].[Local] * Measures.[End Of Day Rate]; 
        End Scope; 
  End Scope;    

  // This is the One to Many section
  // All currency conversion formulas are calculated for the non pivot currency and at leaf of the time dimension   
  Scope( Leaves([Date]) , Except([Reporting Currency].[Currency].[Currency].Members, {[Reporting Currency].[Currency].[Currency].[GBP], [Reporting Currency].[Currency].[Currency].[Local]})); 

    // This section overrides the local values with the Converted value for each selected measures needing to be converted with Measure rate [End Of Day Rate]… 
    // LinkMember is used to reference the currency from the source currency dimension in the rate cube. 
    Scope( { Measures.[Money] } ); 
        This = [Reporting Currency].[Currency].[GBP] / (Measures.[End Of Day Rate], LinkMember([Reporting Currency].[Currency].CurrentMember, [Currency].[Currency])); 
    End Scope;

  End Scope;  // Leaves of time, all reporting currencies but local and pivot currency  
End Scope;  // Measures

[Money] 度量以不同的货币支付，并且每种货币都与一个货币维度和“日终汇率”。

我计算责任的最佳计划是什么？我正在考虑复制 [金钱] 度量，但仅仅为了避免货币转换而添加额外的度量似乎很浪费 - 另外，在真实的多维数据集中还有其他几个需要计算的度量，因此它不仅仅是额外的一。

还有其他人遇到过类似的事情吗？

好的，我最终创建了一个不可见的 [Measures].[Money - Liability]，它没有被上面的代码自动转换，并且我最终在脚本中进行了以下计算：

[Measures].[Liability] = 
(
    SUM 
    ( [Currency].[Currency].[Currency], 
        SUM 
        ( 
            { NULL : [Date].[Date Key].CurrentMember }, 
           (   
                [Money - Liability]
            )
      ) 
      / [Measures].[End Of Day Rate] 
    ) 
    * (Measures.[End Of Day Rate], LinkMember([Reporting Currency].[Currency].CurrentMember, [Currency].[Currency]))
);
