样本数据

我以以下格式导出了 OLAP 多维数据集（测量[Some Percent]用法为Average over time）：

             [Net Weight]   [Some Percent]
             4 387          2,10%
             3 304          1,60%
Grand total: 7 691          1,85% -- Percent is AVG

公式

我需要创建新的计算成员[Modified Percent]，该成员应按以下方式计算：

[Net Weight].[1] / [Net Weight].[Total] * [Some Percent].[1] + 
[Net Weight].[2] / [Net Weight].[Total] * [Some Percent].[2] +
[Net Weight].[n] / [Net Weight].[Total] * [Some Percent].[n] -- can be n rows

带有样本数据的公式

所以我的样本数据将是：

4 387 / 7691 * 2,10 +   |   1,20%
3 304 / 7691 * 1,60     |   0,69%
                    =   |   1,89% -- Sum of percent

期望的输出

[Modified Percent]应按以下方式返回：

             [Net Weight]   [Some Percent]             [Modified Percent]
             4 387          2,10%                      1,20%
             3 304          1,60%                      0,69%
Grand total: 7 691          1,85% -- Percent is AVG    1,89%

MDX 脚本

现在我有MDX Script以下，但[Modified Percent]返回相同的值[Some Percent]

CREATE MEMBER CURRENTCUBE.[Measures].[Modified Percent]
 AS ([Measures].[Net Weight] / sum([Vendor Invoice].[Vendor Invoice No].[All],[Measures].[Net Weight]))  * [Measures].[Some Percent], 
FORMAT_STRING = 'Percent', 
NON_EMPTY_BEHAVIOR = { [Net Weight] }, 
VISIBLE = 1;

也试过这个，但不幸的是，同样的结果：

CREATE MEMBER CURRENTCUBE.[Measures].[Modified Percent]
 AS ([Vendor Invoice].[Vendor Invoice No].CurrentMember,[Measures].[Net Weight]) / 
     iif(
        ([Vendor Invoice].[Vendor Invoice No].CurrentMember.Parent,[Measures].[Net Weight]) = 0,
        ([Vendor Invoice].[Vendor Invoice No].CurrentMember,[Measures].[Net Weight]),
        ([Vendor Invoice].[Vendor Invoice No].CurrentMember.Parent,[Measures].[Net Weight])
        )
      * [Measures].[Some Percent], 
FORMAT_STRING = 'Percent', 
NON_EMPTY_BEHAVIOR = { [Net Weight] }, 
VISIBLE = 1;

看起来像拆分部分返回 1。你有什么想法如何解决它吗？如果有什么不清楚的地方——问我，我会提供更多细节。

问题是计算应用于总（全部）级别，其中[Measures].[Net Weight]等于SUM([Vendor Invoice].[Vendor Invoice No].[All], [Measures].[Net Weight])，因此调整因子为 1.0

尝试将整个块放在多维数据集的 MDX 计算脚本中：

CREATE MEMBER CURRENTCUBE.[Measures].[Modified Percent]
     AS ([Measures].[Net Weight]
         / sum([Vendor Invoice].[Vendor Invoice No].[All], [Measures].[Net Weight]))
       * [Measures].[Some Percent], 
    FORMAT_STRING = 'Percent', 
    NON_EMPTY_BEHAVIOR = { [Net Weight] }, 
    VISIBLE = 1;  

SCOPE ([Measures].[Modified Percent], [Vendor Invoice].[Vendor Invoice No].[All]);
    this = SUM([Vendor Invoice].[Vendor Invoice No].[All].children, [Measures].[Modified Percent]));
END SCOPE;

这会覆盖总数并告诉它对子项求和，而不是重新计算。
