Relationship problem

Good afternoon! I'm very new to Power BI.
I have a problem when I relate two tables to a table, for the same ID, it gives me error "you cannot determine the relationships", unless you relate the two child tables to each other by means of a many-to-many relationship and there it works, is it ok that you relate it like this?

Hi @ihernandez ,

This closed-loop relationship is not allowed in Power BI, which will cause you problems with subsequent report creation, measure creation, etc., so please remove this many-to-many relationship:

Multiple active relationships create conflicts. Multiple relationships may lead to unclear dependencies between tables.
