MDX向本月展示和订购的客户展示，但不是去年的这个月

Question

我正在努力解决mdx看起来想要退回本月订购但未在去年同一月下订单（0美元销售额）的客户。

我将Order Amount作为度量，CustomerId作为维度，Date作为维度。

您需要添加一些您已经尝试过的代码。

在mdx伪代码中，它将是这样的：

  Except(  
    NonEmpty(
       {all members}                      //<<try a function that returns a set such as `.MEMBERS`
       ,(thisMonth, OrderAmountMeasure)   //<<the braces mean this is a tuple made up of two members
    )
   ,NonEmpty(
       {all members}                
       ,(equivMonthLastYear, OrderAmountMeasure)   //<<you could try the .LAG function to go back 12 months
    )
   )

编辑：

  iif(
     equivMonthLastYear = 0,
     null,
  Except(  
    NonEmpty(
       {all members}                      //<<try a function that returns a set such as `.MEMBERS`
       ,(thisMonth, OrderAmountMeasure)   //<<the braces mean this is a tuple made up of two members
    )
   ,NonEmpty(
       {all members}                
       ,(equivMonthLastYear, OrderAmountMeasure)   //<<you could try the .LAG function to go back 12 months
    )
   )
 )
