Reporting services SSRS MDX计算成员忽略筛选器

使用VS2012中的查询设计器，我正在创建一个关于鸡的报告

我选择我的度量（鸡的数量）和维度（农场）

我使用filter expression选项为鸡的颜色创建一个参数，并且只包括红色、蓝色或绿色的鸡。这让我觉得有点像这样：

Farm    |Chicken Count  
A       |3
B       |4
C       |19

Farm    |Chicken Count  |Percentage of Total Chickens at Farm
A       |3              |0.13
B       |4              |1
C       |19             |0.45

With 
  Member [Measures].[Brown Chickens] as ( [Measures].[Chicken Count], [Color].[Brown])
  Member [Measures].[All Chickens] as ( [Measures].[Chicken Count], [Color].[All])
  Member [Measures].[Percentage of Count] as [Measures].[Brown Chickens]]/[Measures].[All Chickens]
Select 
  [Farm].Children on Rows, 
  { [Measures].[Brown Chickens], [Measures].[Percentage of Count] } on Columns
From [myCube]

现在我想展示一下鸡的数量占农场鸡总数的百分比。大概是这样的：

Farm    |Chicken Count  
A       |3
B       |4
C       |19

Farm    |Chicken Count  |Percentage of Total Chickens at Farm
A       |3              |0.13
B       |4              |1
C       |19             |0.45

With 
  Member [Measures].[Brown Chickens] as ( [Measures].[Chicken Count], [Color].[Brown])
  Member [Measures].[All Chickens] as ( [Measures].[Chicken Count], [Color].[All])
  Member [Measures].[Percentage of Count] as [Measures].[Brown Chickens]]/[Measures].[All Chickens]
Select 
  [Farm].Children on Rows, 
  { [Measures].[Brown Chickens], [Measures].[Percentage of Count] } on Columns
From [myCube]

如何创建计算成员以显示最后一个字段

我试过了

[Measures].[Chicken Count]/SUM（轴（1），[Measures].[Chicken Count]）

但这给了我农场鸡的数量，作为所有农场中所有满足参数的鸡的百分比

我面临的问题是，我找不到一种方法来获取农场所有的鸡——忽略过滤器

我怎么能做这样的事情

[措施][鸡数]/总数（非过滤鸡）

请让我知道在评论中，如果有什么我可以做，以帮助进一步解释这一点。

还请假设（如果还不清楚的话）我几乎不了解MDX。

假设您的过滤器基于[Color]维度，并且您只过滤棕色鸡，您可以这样定义它：

Farm    |Chicken Count  
A       |3
B       |4
C       |19

Farm    |Chicken Count  |Percentage of Total Chickens at Farm
A       |3              |0.13
B       |4              |1
C       |19             |0.45

With 
  Member [Measures].[Brown Chickens] as ( [Measures].[Chicken Count], [Color].[Brown])
  Member [Measures].[All Chickens] as ( [Measures].[Chicken Count], [Color].[All])
  Member [Measures].[Percentage of Count] as [Measures].[Brown Chickens]]/[Measures].[All Chickens]
Select 
  [Farm].Children on Rows, 
  { [Measures].[Brown Chickens], [Measures].[Percentage of Count] } on Columns
From [myCube]

使用以下表达式将计算出的度量值添加到查询中：

[Measures].[Chicken Count] / ([Measures].[Chicken Count], [Chicken].[Colour].[All])

分母中的元组删除了按颜色对鸡的局部过滤（假设维度的名称为“Chicken”，属性为“color”），返回给定上下文中鸡的总数

类似地，如果您想要农场占鸡总数的百分比，您可以这样做：

[Measures].[Chicken Count] / ([Measures].[Chicken Count], [Chicken].[Colour].[All], [Farm].[Farm].[All])

这正是我想要的。太简单了！
