How to do this?

[tusa]

I have made these lists, but how to connect the fields as shown, is that with joints?

Best regards Tue.

Yes, list joins:

In you case
- from sendeplan.sendeplan_produktion to produktion.produktion_id
and another join
- from produktion.produktion.pgmserie to pgmserie.pgmserie_id

At least that's how it seems quickly looking at your screenshot.
