Hey Folks,
I managed to find the first text value in a column with this dax formula:
firsttextvalue = TOPN(1,VALUES('table'[columnname])) --> TOPN because my table is already organized
what is the formula to find the second text value in the same column? I do not mean the second row value, because there is no information which row contains the next different text.

    Hi @pbiexpert

    Assuming problem understood

    61774-demo.png

    SecondTextVal :=
    VAR FirstTextVal = [firsttextvalue] // Your existing measure
    RETURN
    CALCULATE (
    TOPN ( 1, VALUES ( 'table'[columnname] ) ),
    FILTER ( 'table', 'table'[columnname] <> FirstTextVal )
    )

    Hi,

    From the top function you used , did you mean that you want to find the second biggest value in that column ?

    If so,
    You could try :
    =MINX(
    TOPN(2,VALUES('table'[columnname]))
    )

    If you want to dig deep for Nth value in a column you could try more sophisticated solution like this : display the top N elements

    Regards,
    Lukas

    Many thanks for your fast reply! Yes @Lz._ , your approach is the winning one, it gave me back exactly the second different text that I was looking for. The formula MINX did not work, I bet it is because I have text in the column and MINX is used for determining values. Thanks a lot! :)
