将sql排名转换为mdx排名

Question

这是我的sql代码--我想把它转换成mdx查询。也可以将这些结果集用于power bi报告中。我无法将此sql查询写入mdx查询。有人能帮我吗？

    Select * From(
    Select 
    dense_RANK()over(partition by t.MonthName order by t.amount desc)rank
    ,t.*
    From( 
    Select DSP.SalesPointShortName ,dd.MonthName 
    ,SUM(fs.salesAmount)Amount
      From FactSales FS
    INNER JOIN DimDate dd on fs.DateKey=dd.DateKey
    INNER JOIN DimSalesPoint DSP on DSP.SalesPointID=FS.SalesPointID
    group by dsp.SalesPointShortName ,dd.MonthName 
    )as t  
    )as f where f.rank=1

我的预期输出是：
