ssas - 我该如何解决这个 MDX 问题？

Question

我想比较以前的值和当前的值，但是我的 MDX 查询给出了以下错误

"The CURRENTMEMBER function expects a hierarchy expression for the 1 argument."  

我该如何解决这个问题？

我的 MDX 查询如下。请帮忙

with member [Measures].[Growth] as ([Date].[Calendar].[Month].CurrentMember,[Measures].[Internet Sales Amount])-([Date].[Calendar].[Month].CurrentMember.PrevMember,[Measures].[Internet Sales Amount])
select
{[Measures].[Internet Sales Amount],[Measures].[Growth] }
on columns,
{([Date].[Calendar].[Month].Members)}
on rows
FROM [Adventure Works]

Answer 1

将您的成员(member)声明更改为以下内容:

with member [Measures].[Growth] as ([Date].[Calendar].CurrentMember,[Measures].[Internet   Sales Amount])-([Date].[Calendar].CurrentMember.PrevMember,[Measures].[Internet Sales Amount])

currentmember 函数在层次结构中工作。
