如何计算 DATES 层次结构中选定成员的“FactInternetSales”表中的销售总数？

(
[Order Date].[DATES].CURRENTMEMBER, 
COUNT(DISTINCT([Fact Internet Sales].[Sales Order Number].[Sales Order Number]
)

Answer 1

尝试在外面用额外的大括号来表示一组元组：

COUNT(
  {  
    [Order Date].[DATES].CURRENTMEMBER
    *
    [Fact Internet Sales].[Sales Order Number].[Sales Order Number]
  }
)

Answer 2

with set abc as
EXISTS([Fact Internet Sales].[Sales Order Number].[Sales Order Number], 
[Order Date].[DATES].CURRENTMEMBER,
"Fact Internet Sales"
)

member [Measures].[Count]
AS Count(Distinct(abc))

SELECT  [Measures].[Count] on 0
from [YourCube]
WHERE Order Date].[DATES].&[01/01/2015] --Some random value for slicer
