New column counting values from two different tables

Hello,

This is my fitst post, I hope I can get the help I need. This is my case:

 

I have Table Enrollments linked to Quiz and to Excersise. Type A or B define whether the user did a Quiz (A) or an Excecise (B).

I need a new column Attempts in Enrollments that tells me:

1. How many times one Quiz (Type A) was executed by a user

2. How many times one Excersise (Type B) was executed by a user.

 

Like this:

LOOKUPVALUE does the work but it's extremley demanding for my model and I need a better approach.

 

Thanks for your help!

Hi @rgalvez ,

 

You can create the following calculated column:

 

Attempts = SWITCH(Enrollments[Type],"A",CALCULATE(COUNTROWS(Quiz),FILTER(Quiz,Quiz[UserID] = EARLIER(Enrollments[UserID]))),"B",CALCULATE(COUNTROWS(Excersise),FILTER(Excersise,Excersise[UserID] = EARLIER(Enrollments[UserID]))))+0

@rgalvez you can simply add two measure and use it in the table visual

 

Count Attempts = COUNTROWS ( TableAttempt )

Count Exercise = COUNTROWS ( TableExercise )

 

To visualize, use table visual, put column from user table and above measures.

I don't think this option helps. I need the two measures in the table, not in the view.
