RANK not working with specific columns

[tkiwi]

Hey everyone, I wanted to share an issue I encountered while working with the DAX RANK function in Power BI.

I noticed that this function works with some columns from my dimension, but not with others in the same dimension.

So here is my working code

__Rank =
var _relevantProducts =
    ADDCOLUMNS
    (
        ALLSELECTED ( Produkte[StabileArtikelNr mit Nummer] )
        , "@Umsatz", [Umsatz]
    )
 
RETURN
IF (NOT ISBLANK([Umsatz] )
    ,
        RANK
        (
            DENSE
            , _relevantProducts
            , ORDERBY
            (
                [@Umsatz]
                , DESC
                , Produkte[StabileArtikelNr mit Nummer]
                , ASC
            )
        )
    )

So my ranking works as expected

But now, if I want to use another column from the same dimension in the matrix and change also my code to

__Rank =
var _relevantProducts =
    ADDCOLUMNS
    (
        ALLSELECTED ( Produkte[Stabile ArtikelNr Bezeichnung] )
        , "@Umsatz", [Umsatz]
    )
 
RETURN
IF (NOT ISBLANK([Umsatz] )
    ,
        RANK
        (
            DENSE
            , _relevantProducts
            , ORDERBY
            (
                [@Umsatz]
                , DESC
                , Produkte[Stabile ArtikelNr Bezeichnung]
                , ASC
            )
        )
    )

I get the following result:

As you can see, I only changed the column in my ALLSELECTED()-Part and in the RANK-Part.

Has anyone else experienced this issue or is there something wrong in my code?

Looking forward to hearing your thoughts and suggestions. Thanks!

Hi @tkiwi ,

Based on the description, for the Stabile ArtikelNr Bezeichnung column , the rows have the same ranking. It is normal for the row to have the same ranking when using rank dax.

Rank function have some limitations. If the columns specified within orderby and partitonby cannot uniquely identify every row in relation, then two or more rows may have same ranking.

Then, try to verify the data type of the column and check the values.

Besides, ALLSELECTED function gets the context that represents all rows and columns in the query.
