我该如何解决这个MDX问题？

Question

我想比较之前和当前的值，但我的MDX查询给出以下错误

"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

将您的会员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])

当前成员函数在一个层次结构中起作用。
