Hi,
For a project in CPM4 I need to configure the cardinalities in a 1-1 table relationship. Unfortunately, Celonis detects the wrong table (for my use case) as the parent table, making the desired calculations impossible. Is there an option / trick similar to what David described in the answer of the first question in Process Data Model (relationship activity - case table )

  1. On the edge, it shows how you have configured the join. If you click on the edge, you will see that you have configured Activities as the 1-side of the Join, and Cases as the N-side of the join. I would suggest to use the Swap Tables option in the Foreign key settings to configure it in the correct way. Then, the cardinalities will be shown as you expect.


I already tried redefining the key and swapping the left and right hand table (and reloaded the DM), however this didnt make a difference.
Thanks, best regards,
Lucas
Hi Lucas,
also in CPM4 it should be possible to solve it by swapping the foreign key in the Data Model. If that doesnt help, maybe you actually have a 1:N/N:1 relationship in your data? Did you make sure that you actually have a 1:1?
Best
David
