Creating an entry then adding it to another entry

[khaledkherallah]

So I made a button that creates a new entry, and this entry is a data type of a field of another entry.

And then added another workflow that adds the new entry to the other entry list.
I used these workflows.

But it doesn’t seem to work, When I check the main entry I cant see the vehicle added to the list after I pressed [not on the front end not the back end].

Please Help

I found out a good solution, the key is constraints and reversing data searches
