Hi Everyone.
I'm kind of new to Power BI, but i've been working hard on a report these days.
My problem is: I have a fix reference table and an answers table (based on a key) shown bellow
'Reference'
Fixed Answers |
A |
B |
C |
D |
E |
'Answers'
Key | Answer |
1 | A |
1 | C |
2 | A |
2 | D |
3 | B |
What I'm trying to do is get the following table:
'Final I want'
Key | Missing answer |
1 | B,D,E |
2 | B,C,E |
3 | A,C,D,E |
Either on separated rows or in the same cell works for me, but I just can't seem to get it...
I even get a list of missing values, but not related to the key. what I got was:
'Table I got'
Missing Answers |
E |
Can anyone help?

Hi @Quartarolo
0. Change the name of the Reference[Fixed Answers] column to Reference[Answer]
1. Place Answers[Key] in the a table visual
2. Create this measure and place it on the visual
Missing answer =
VAR answers_ =
DISTINCT ( Answers[Answer] )
VAR refAnswers_ =
ALL ( Reference[Answer] )
VAR missing_ =
EXCEPT ( refAnswers_, answers_ )
RETURN
CONCATENATEX ( missing_, [Answer], ", " )

Hi @Quartarolo - Sorry your question is not clear to me.
Can you please explain what's the logic applied for 'Final I want' ?
All i understand is There is a reference table with values A to E
'Answers' table? What does this mean? How A and C has the same key value 1? And A and D has 2
Totally confusing to me
Please be more elaborative.
Cheers,

Sorry, it's my first post! I'll elaborate more:
the 'Answers' table is from a form filled by my costumer. In there, they choose a location (the 'key" column), and choose a safety item that was installed (those are the answers).
The thing is that not all items are installed at the same time, so there is more than one row for each location.
I'll rewritte the tables:
'Reference'
Safety Item |
A |
B |
C |
D |
E |
'Costumer Answers'
Key (Location) | Answer (Safety Item installed) |
1 | A |
1 | C |
2 | A |
2 | D |
3 | B |
So what i want to know is "which items haven't been installed on each location"
If it's still confusing, just let me know, and thanks for the help!
