There are 2 things you could do here:
The first option is the easiest one, but it's up to you to see what works best for you.
Hope this helps. With kind regards,
If you open the Department and Employee entities, you can set it to a persistable entity (see screenshot)

Thanks for your response.
I tried Option 2, as I am not aware of how to perform Option 1 (if possible attach a screenshot)
I got below error and also I have put the dialogue screenshot.
Previously, when I had selected ‘Find an object (by key)’. I got an error as shown below.
For the option 1 (as mentioned by Bryan) you need to go to the domain model of the module.
So not in the Import Mapping.
There you can select the entity itself and open the properties (and you will see what he is showing in his screenprint).
Hope that I could help!
