在 MDX 中使用 case-when 时的 Total 错误答案

【问题标题】：wrong Total using case-when in MDX在 MDX 中使用 case-when 时的 Total 错误
【发布时间】：2016-05-28 08:00:34
【问题描述】：

如果我使用以下负总数而不是前一个，我将获得相同的输出，但仍然不是我的预期输出。有没有人可以帮帮我？

MEMBER [Measures].[Negative Total] AS
CASE
    WHEN ([Measures].[Total],[Dim Account].[Account Marketing].&[Income]&[Marketing]) < 0
    THEN [Measures].[Total]*-1
    WHEN ([Measures].[Total],[Dim Account].[Account Marketing].&[Income]&[Marketing]) > 0
    THEN 0
END

让我解释一下我想要实现的目标。我有一个 [Dim Account] 维度，它具有 [Account Type]、[Account Activity]、[Account Marketing] 等属性。[Account Type] 是收入、费用、.. [Account Activity] 就像广告、折扣, 赞助销售等 [Account Marketing] 是这些东西的组合，我的意思是广告是费用，而折扣存储为负收入，因此最终折扣将被视为营销费用这就是为什么我的会员 [Negative Total] 正在转换收入乘以-1，我想排除这些收入是正数，因为它们是收入。我只想显示那些转换后的收入，最后把它们加起来。在我的 MDX 中，数据显示完美，但将原始值 -43380.4 +18 - 9181.32= -52542.81 相加，应该是 43380.4 +0 +9181.32= 52561.72。为了将原始总数与预期总数进行比较，我同时显示了 [Measure].[Total] 和 [Measure].[Negative Total]。知道诀窍的请帮帮我

    THEN [Measures].[Total]*-1

        [Dim Account].[Account Marketing].Properties("Account Type") ="Income" AND
        [Measures].[Total]>1

我认为这是一个棘手的问题，我试图整理一个月。请帮我修好。提前致谢

由于[All] 也是会员，它按预期工作。

要达到您想要的效果，请添加一个获得负总数的基本度量，然后在最终计算中使用它。

MEMBER [Measures].[Negative Total Test] AS
CASE
    WHEN ([Measures].[Total],[Dim Account].[Account Marketing].&[Income]&[Marketing]) < 0
    THEN [Measures].[Total]*-1
    WHEN ([Measures].[Total],[Dim Account].[Account Marketing].&[Income]&[Marketing]) > 0
    THEN 0
END

MEMBER [Measures].[Negative Total] AS
CASE
    WHEN [Dim Account].[Account Activity].CURRENTMEMBER IS  [Dim Account].[Account Activity].[All]
    SUM(
        [Dim Account].[Account Activity].[Account Activity].MEMBERS,
        [Measures].[Negative Total Test]
       )
   ELSE [Measures].[Negative Total Test]
END

(upped) 不错的答案 Sourav
我已经在另一个用户@shamim 下发布了我的真实但非常接近这个解决方案。请看一下

【解决方案2】：

（只是为了添加到 Sourav 的好解决方案中）

CASE 和 IIF 都很慢 - IIF 在某些情况下可能更快，通常如果它的分支之一可以是 NULL 是更快的选择：

MEMBER [Measures].[Negative Total Test] AS
  IIF(
    (
       [Measures].[Total]
      ,[Dim Account].[Account Marketing].&[Income]&[Marketing]
    ) >= 0
      ,NULL
      ,[Measures].[Total] * -1
  )
MEMBER [Measures].[Negative Total] AS
  IIF( 
    [Dim Account].[Account Activity].CURRENTMEMBER 
       IS [Dim Account].[Account Activity].[All]
    ,SUM(
        [Dim Account].[Account Activity].[Account Activity].MEMBERS,
        [Measures].[Negative Total Test]
       )
   ,[Measures].[Negative Total Test]
  )

根据屏幕截图，不需要在第一个计算中包含营销，因此可以进一步简化：

MEMBER [Measures].[Negative Total Test] AS
  IIF(
    [Measures].[Total] >= 0
   ,NULL
   ,[Measures].[Total] * -1
  )
MEMBER [Measures].[Negative Total] AS
  IIF( 
    [Dim Account].[Account Activity].CURRENTMEMBER 
       IS [Dim Account].[Account Activity].[All]
    ,SUM(
        [Dim Account].[Account Activity].[Account Activity].MEMBERS,
        [Measures].[Negative Total Test]
       )
   ,[Measures].[Negative Total Test]
  )

感谢您提供替代 IIF 解决方案而不是 Case-When 然而，这个问题实际上是我主要问题的一部分。我还有另一个需要使用 case-when 条件检查的条件。很快我将在另一篇文章中发布我的整个问题，然后你会看到并尝试解决整个问题。你们真是乐于助人。感谢您的关心
我刚刚检查了您的解决方案并且工作正常。再次感谢
你能看看上面的答案吗，这确实是个问题，我还在苦苦挣扎

哇！我得到了答案，这就是我要找的东西。什么都没有，只是改变了【阴性总测试】的显示。我再次感谢 Saurav，因为他给了我 MDX 代码的生命。

我应该问另一个问题，但是我已经达到了我的问题限制，对此感到抱歉。上述问题是我问题的一部分。最终的输出应该和我编辑的图片一样。根据 Sourav 的解决方案，他检查了 [Dim Account].[Account Activity].CURRENTMEMBER IS [Dim Account].[Account Activity].[All] 的条件，这完美地解决了这个小问题，但是当我想用原始收入积累时(650,920.88) 然后它会出现出乎意料的大数字。我需要的另一个解决方案我想将营销费用（24010.44）与已经转换的负营销收入（43380.4+9181.32）相加，所以最终结果应该是 76572.16。请修改我的 MDX。非常感谢

【讨论】：

@SouravA 你能看看吗，我还在挣扎
@SouravA 我注意到如果我使用 WHEN [Dim Account].[Account Activity].CURRENTMEMBER IS [Dim Account].[Account Activity].[All] THEN SUM( [Dim Account].[ Account Activity].[Account Activity].MEMBERS, [Measures].[Negative Total Test] ）这条线连同我的总代码实际上是 [Dim Account].[Account Activity].[All] 的两倍，这就是为什么总数是 1269026 而不是 650920
