Join table or list field for many to many relationship

@boston85719 Thank you guys for your responses.
I was worried about the performance, since it’s strongly not recommanded to create a list in SQL. But as I understand, there is no problem in that case since it’s pointing directly to the object itself.

So I can create two list fields, Thank you !

@NigelG Yeah, I’ve read many of your posts that helped me understand ! Thanks :slight_smile:
