    Hi smpa01 ,

    I updated your sample pbix file(see the attachment), please check if that is what you want. You can create a measure as below to get the rank...

    Measure = 
VAR tab =
    FILTER (
        ALLSELECTED ( 'wc' ),
        'wc'[Win] <> 0
            && 'wc'[Region] = SELECTEDVALUE ( 'wc'[Region] )
    )
VAR result =
    SUBSTITUTEWITHINDEX (
        'wc',
        "rank", SUMMARIZE ( tab, 'wc'[Win] ),
        'wc'[Win], DESC
    )
VAR _rank =
    MAXX ( result, [rank] )
RETURN
    IF ( ISBLANK ( _rank ), BLANK (), _rank + 1 )

    In addition,  you can achieve the same requirement using RANKX function. Please create a measure as below to get it, it is easier...

    Rank =
RANKX (
    FILTER ( ALLSELECTED ( 'wc' ), 'wc'[Region] = SELECTEDVALUE ( 'wc'[Region] ) ),
    CALCULATE ( SUM ( 'wc'[Win] ) ),
    ,
    DESC,
    DENSE
)

    Best Regards

    This feels a bit for efficient since it's iterating over regions instead of every row:

    Table 3 =
SELECTCOLUMNS (
    GENERATE (
        SUMMARIZE ( wc, wc[Region] ),
        VAR _Region = wc[Region]
        VAR _Partition_ =
            SELECTCOLUMNS ( FILTER ( wc, wc[Region] = _Region ), wc[Country], wc[Win] )
        VAR _AddCol_ =
            ADDCOLUMNS ( _Partition_, "@win", wc[Win] )
        VAR _SubIndex_ =
            SUBSTITUTEWITHINDEX (
                _AddCol_,
                "Rank", SUMMARIZE ( _AddCol_, [@win] ),
                [@win], DESC
            )
        RETURN
            _SubIndex_
    ),
    "Region", wc[Region],
    "Country", wc[Country],
    "Win", wc[Win],
    "Rank", [Rank] + 1
)

Hi smpa01 ,

Please update the formula of measure as below and you can get the desired result... You can find the details in the attachment.

Measure = 
VAR filt =
    FILTER ( ALLSELECTED ( 'Table' ), 'Table'[cat] = "cat1" )
VAR new2 =
    SUBSTITUTEWITHINDEX (
        'Table',
        "rank", SUMMARIZE ( filt, 'Table'[row] ),
        'Table'[row], 1
    )
RETURN
    MAXX ( new2, [rank] )

Best Regards

    Anonymous  many thanks !!! well done. 

    Just wondering, if it is possible to achieve a ranking by a partition with SUBSTITUTEWITHINDEX 

    E.g.

     

    wc table

| Region        | Country   | Win |
|---------------|-----------|-----|
| South America | Brazil    | 5   |
| South America | Argentina | 3   |
| South America | Chile     | 0   |
| South America | Uruguay   | 2   |
| Europe        | Germany   | 4   |
| Europe        | Italy     | 4   |
| Europe        | Austria   | 0   |

end goal - Ranking of Win by Region Partition

| Region        | Country   | Win | Rank |
|---------------|-----------|-----|------|
| South America | Brazil    | 5   | 1    |
| South America | Argentina | 3   | 2    |
| South America | Uruguay   | 2   | 3    |
| Europe        | Germany   | 4   | 1    |
| Europe        | Italy     | 4   | 1    |

     

    pbix is attached

        Anonymous  I know how to achieve the same with RANKX. I just wanted to see how can I do the same with a different DAX function
