    You should use EARLIER() in your filter:

     

    Column =
CALCULATE (
    FIRSTNONBLANK ( Table4[Column C], TRUE () ),
    FILTER (
        Table4,
        Table4[Column A] = 1
            && Table4[Column B] = EARLIER ( Table4[Column B] )
    )
)

You can try the FIRSTNONBLANK function instead of LOOKUPVALUE.  This would look like:

 

CALCULATE(
   FIRSTNONBLANK(ColumnC, TRUE()),
   FILTER(Table, ColumnA = ColumnB)
)

Hello

 

I tried what u said and used

=CALCULATE(
   FIRSTNONBLANK('Table'[Column C]; TRUE());
   FILTER('Table';'Table'[Column A]=1);
   FILTER('Table';'Table'[Column B]='Table'[Column B])
)

It works half. It ignores kinda the second Filter, so the output currently is "P 1" for every line. If i replace the second 'Table'[Column B] with the actual Value of the Row (e.g. 99 for the first row, 88 for the second one...) it shows the correct value. 

 

Any other Ideas?

      Hi, All

       

      I have used this approach and it is partly working for me. I would like to extract the the value of the column Z_result by filtering in Variable 1 and Variable 2 (first value of Z_Results when the values of Variable 1 and Variable 2 are equal). 

       

      By using FIRSTNONBLANK function, I am not getting what I want (see Unique ID 7 and 8 in the attached picture).

       

      The attached pic is just an oversimplication of a much more complex set of data with 1000s of rows

       

      Thanks for your help

       

      ------------------------------

       

      ZZ_First Occurence =
      CALCULATE (
      FIRSTNONBLANK(Sheet1[Z_Resul],TRUE()),
      FILTER (
      Sheet1,
      Sheet1[Variable 1] = EARLIEr ( Sheet1[Variable 1] )
      && Sheet1[Variable 2] = EARLIEr ( Sheet1[Variable 2] ) ))

      I am working on a patient flow projected and was having such a hard time looking up the earliest date of a consult based on patient number and visit code (consult vs. treatment vs. simulation). This solution worked for me! Thank you so much.
