Creating Relationships within same Models

I’m trying to build a course catalog with certain classes or courses pointing to other classes or courses. How can I create a relationship of one model pointing to itself?

The diagram allows me to create a physical recursive pointer, but when I try to edit that relationship, it won’t allow me to save changes?

Am I missing a certain constraint or step?

Hi Bart,

When you create such a relationship you need to make sure both ends of the relationship have unique names - e.g. “Course” and “PrerequisiteCourse”.

Let me know if this solves your problem!
