SQL & PL/SQL

I have a strange problem.

I have a table EMP_MASTER . Whenever I am trying to delete a record from this table, I am getting Maximum no. of open cursor exceeded error. But this error doesnot come when i delete from any other tables. And no. of open cursor is much lesser than OPEN_CURSOR parameter.

All other tables (around 700) has foreign key constraint to this EMP_MASTER table for created_user paramater.

Is it some thing like, when I am trying to delete a record from EMP_master, implicit cursor opens up and checks all referenced tables. and that limit gets exceeded ?

Please help.

Thanks,
Raj
