DAX - RANK Функция

Question

У меня есть код RANK от WEBI и вам нужно написать аналогичный код в DAX или MDX. Оба могут работать. Но DAX будет более полезен.

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

Я пробовал код ниже в DAX, но это не то, что мне нужно.

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

Можете ли вы мне помочь написать?

Grouping by Count. This is extra.

Answer 1

Я не очень хорошо DAX, но MDX способ заключается в следующем:

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

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

Member [Measures].[RankDenseSet] as 
Rank(
