Answer 1

I don't think you can cause its a parent key violation.
Do you want to store the ora_errors exceptions?You need to embed that in PL?SQL and create a log table.
Procedure insert_into_destination_table IS
          start_time date :=sysdate;
          proc_name varchar2(40) :='Insert_into_destination_table';
          cnt integer :=0;
Begin
insert into      Table Destination
values('AAA');
     add_log(proc_name, cnt, start_time, 'Finish!');
          EXCEPTION
               WHEN OTHERS THEN
                    rollback;
               add_log(proc_name, cnt, start_time, substr(SQLCODE||' '||SQLERRM, 1, 199));     
Cheers!
