DAX - RANK功能

Question

我有一个来自WEBI的RANK代码，需要在DAX或MDX中编写类似的代码。两者都可以工作。但DAX会更有用。

=Rank([OrderCount];([Category1];[Category2];[Category3])) 

我已经在DAX下面的代码尝试，但它不是确切的我需要什么。

=RANK.EQ(table1[OrderCount];table1[OrderCount]) 

你能帮我写出类似吗？

Grouping by Count. This is extra.

Answer 1

我不是在DAX很好，但MDX方法如下：

with 
Dynamic Set OrderedSet as 
Order(
    NonEmptyCrossJoin(
     [Dim Product].[Subcategory Name].[Subcategory Name].Members, 
     [Dim Product].[Category Name].[Category Name].Members 
     [Measures].[Order Quantity], 
     2 
    ), 
    [Measures].[Order Quantity], 
    BDESC 
) 

Member [Measures].[Rank] as 
Rank(

     ([Dim Product].[Subcategory Name].Currentmember, 
     [Dim Product].[Category Name].Currentmember), 
     OrderedSet 
) 

select 
{[Measures].[Order Quantity],[Measures].[Rank]} on 0, 
non empty OrderedSet on 1

DenseRank：

with 
Dynamic Set OrderedSet as 
Order(
    NonEmptyCrossJoin(
     [Dim Product].[Subcategory Name].[Subcategory Name].Members, 
     [Dim Product].[Category Name].[Category Name].Members, 
     [Measures].[Order Quantity], 
     2 
    ), 
    [Measures].[Order Quantity], 
    BDESC 
) 

Dynamic Set DenseOrderedSet as 
Order(
    NonEmpty(
     OrderedSet, 
     [Measures].[RankFirstMatch] 
    ), 
    [Measures].[Order Quantity], 
    BDESC 
) 

Member [Measures].[Rank] as 
Rank(
    ([Dim Product].[Subcategory Name].Currentmember,[Dim Product].[Category Name].CurrentMember), 
    OrderedSet 
) 

Member [Measures].[RankFirstMatch] as 
IIF(
    [Measures].[Order Quantity] 
    = 
    (
     OrderedSet.Item([Measures].[Rank] -2), 
     [Measures].[Order Quantity] 
    ), 
    NULL, 
    [Measures].[Rank] 
) 

Member [Measures].[RankDenseSet] as 
Rank(
    ([Dim Product].[Subcategory Name].Currentmember,[Dim Product].[Category Name].CurrentMember), 
    DenseOrderedSet 
) 


Member [Measures].[DenseRank] as 
IIF(
    [Measures].[RankDenseSet] = 0, 
    (OrderedSet.Item([Measures].[Rank] -2),[Measures].[DenseRank]), 
    [Measures].[RankDenseSet] 
) 


select {[Measures].[Order Quantity],[Measures].[Rank],[Measures].[RankFirstMatch],[Measures].[RankDenseSet],[Measures].[DenseRank]} on 0, 
non empty OrderedSet on 1
