Create a temp. column using VAR.

Hey everyone, 


I want to create a measure where i want to create an extra column that says if(Column A <> blank() , 1 , 0), after that i want a rate of how many 1's there are. 
Something like this: 



I know that i can just create an calculatedcolumn in the table, but I dont want a messy table with a lot columns, therefore i would prefer to do this in the measure. 

Hope some of you can help :))) 

Thanks

    Hey Anonymous ,

     

    I think you were pretty close. With a SUMX instead of a SUM it should work:

    CompanyAnswerRate =
VAR _ANSWER =
    SUMMARIZE (
        'TrustPilot - Review',
        'TrustPilot - Review'[comanyReplyText],
        "AnswerYesNo", IF ( 'TrustPilot - Review'[companyReplyText] <> BLANK (), 1, 0 )
    )
VAR AnswerRate =
    DIVIDE (
        SUMX ( _ANSWER, [AnswerYesNo] ),
        COUNTROWS ( _ANSWER )
    )
RETURN
    AnswerRate

     

    By the way it's not recommended, to do calculations within SUMMARIZE as there could be wrong results. The new standard is to use ADDCOLUMNS to calculate in combination with SUMMARIZE. See the following article for more details:

    If you need any help please let me know.
    If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍
