I dont want a key field in my visual. Next to that. I think that Bridge Tables should be hidden tables. They are there so i can avoid N:M relationships.

 

Since it is not working for me i switches to N:M relationships.

 

Thanks anyways

Hi @Anonymous ,

 

Based on my test, please do not drag the related Key field to visuals:

If you want, you need to use the Key field from the Bridge table , as shown below:

As i said. Changing directions doesnt work.

Single Directional and one to many is what the picture shows.
