Input Yes for whole column

[botaac]

Hello Everyone,

I am trying to create a column with DAX expression that inputs Yes when a student fails an exam for a certain period. For example, I have the following table

Name	Exam	Exam Score
Steve	Exam 1	Fail
Steve	Exam 2	Pass
Steve	Exam 3	Pass
Bob	Exam 1	Pass
Bob	Exam 2	Fail
Bob	Exam 3	Fail
Jeff	Exam 1	Fail
Jeff	Exam 2	Fail
Jeff	Exam 3	Fail

I wanted to create an additional column called Exam 1 Fail? and it will put Yes for each row if they failed Exam 1. The result table would be:

Name	Exam	Exam Score	Exam 1 Fail?
Steve	Exam 1	Fail	Yes
Steve	Exam 2	Pass	Yes
Steve	Exam 3	Pass	Yes
Bob	Exam 1	Pass	No
Bob	Exam 2	Fail	No
Bob	Exam 3	Fail	No
Jeff	Exam 1	Fail	Yes
Jeff	Exam 2	Fail	Yes
Jeff	Exam 3	Fail	Yes

How would I go about doing this? I have tried IF statements but I'm having a tough time finding the correct logic that would but Yes for each row. Any help is much appreciated and let me know if I can clarify.

Hi,

This calculated column formula works

=if(CALCULATE(COUNTROWS(Data),FILTER(Data,Data[Name]=EARLIER(Data[Name])&&Data[Exam]="Exam 1"&&Data[Exam Score]="Fail"))>=1,"Yes","No")

Hope this helps.

Hi @botaac 

You could use something like this.

Fail exam 1 = 
VAR Student = Exams[Name]
VAR Resultexam1 = COUNTROWS( 
    FILTER( Exams, Exams[Name] = Student && Exams[Exam] = "Exam 1" && Exams[Exam Score] = "Fail"))
RETURN 
If(Resultexam1 = 1,"Yes","No")

Best regards,

Jeroen
