How to insert an object in doctrine, without persisting in other tables?

I am trying to insert a record into a table that contains compound key. This is the error:

  

"A new entity was found through the relationship   'EnFOperEstadoBean # grupoCompanica' that was not configured to cascade   persist operations for entity:   EnGroupBean @ 000000000183abf100000000178339a6. To solve this   issue: Either explicitly call EntityManager # persist () on this unknown   entity or configure cascade persist this association in the mapping   for example @ManyToOne (.., cascade = {"persist"}). If you can not find out   which entity causes the problem to implement   'EnFGroupBean #__ toString ()' to get a clue. "

Well, if I put cascade={"persist"} , it tries to create record in other tables. Do you have any option for him to do nothing? I tried the detach to remove the relationships with other tables, however it gives error again.

To the codes ...
