Joining 1-1 tables how


We have 2 Data Models both with the same customer table.
In the first data model I have customer_credit with a 1-1 relation with the customer table. Celonis links them in the data model as 1-n (customer-customer_credit)

However in the second data model the same 2 tables are linked with n-1 (customer-customer_credit).

How can I ensure the link is 1-n when the tables are 1-1?


Hi @JoaoFrancisco,

could you please check whether you have defined the source and target table in your data models in the same manner?

I would assume that the definition on how to join the tables might be different.

Hopefully that’ll solve your issue!
