I am working on a data model in Qlik Sense where I have two fact tables (EventsForCalendar and int_ausap) and want to connect them through a Link Table.

🔎 Goal:

Create a Link Table using %Key_Field (which is a combination of Kundennummer and Produktgruppe).
Ensure that if a Produktgruppe has multiple values, they are split into separate rows.
Avoid synthetic keys.

🚨 Issue:

If I rename Kundennummer and Produktgruppe in the fact tables, I get synthetic keys.
If I drop them from the fact tables, the tables are not properly connected via the Link Table.

Hi,

It seems the 2 fact tables have the same key. I would :
- keep a key in each fact table with a different name
- create the link table with the 2 keys + Kundennummer and Producktgruppe.
- remove form fact tables the fields Kundennummer and Producktgruppe.

Model could look like :

It could help to add a %FactType in the link table (useful when you will create your measures in the app)

I hope it will help.
