mdx计算的度量与度量

Question

只是想知道你是否可以向我解释为什么这两个mdx语句产生不同的结果，以及我如何改变计算的度量是正确的。我假设计算的度量使用sum函数是错误的。

SELECT    
{ 
[Measures].[PPPH]
} 
ON COLUMNS,  
{
[Matter].[Parent Matter Lawyer - Responsible].&[qnas]
}
ON ROWS  
FROM [Expert Hypercube] 
WHERE   
(  
[Date].[Fiscal].[Month].&[201702], 
[Relative Period].[Relative Period].&[YTD]
) 

与

with 
member measures.[PPPHx] as 
  sum({{linkmember([Timekeeper].[Person].currentmember,[Matter].[Parent Matter Lawyer - Responsible])}},measures.[PPPH])
select
{
measures.[PPPHx]
} on columns, 
{
[Timekeeper].[Person].&[qnas]
} on rows
from [Expert Hypercube]
where
(
[Date].[Fiscal].[Month].&[201702], 
[Relative Period].[Relative Period].&[YTD]
)

Answer 1

目前还不清楚为什么要使用 Sum 功能。 LinkMember 函数返回一个成员，不需要像{...}一样覆盖它。你还需要使用All成员，因为它返回 [Timekeeper]。[Person] .CurrentMember + LinkMember（[Timekeeper]。[Person] .CurrentMember，[Matter]。[Parent]物质律师 - 负责任]] 。

With 
Member [Measures].[PPPHx] as 
(
    LinkMember([Timekeeper].[Person].CurrentMember,[Matter].[Parent Matter Lawyer - Responsible]),
    [Timekeeper].[Person].[All],
    [Measures].[PPPH]
)
