I have a person X (student) related to 2 courses:
- Course with attribute code: MATH and relationship attribute grade: 90. This means that the student got 90 points in math.
- Course with attribute code: GEO without the relationship attribute grade (it doesn't exist). This means that the student hasn't been graded in geography yet.
I created a segment with all of the following conditions:
- Courses attribute code is equal to MATH.
- Relationship attribute grade does not exist.
The person X is matching the criteria and it's included in the segment, but it should not. I just want to select the students that haven't been graded in math yet.
What am I doing wrong?
Thanks in advance!
