Ora-0000 when submitting a concurrent program from DB trigger

Question

Hello,
I am getting following error when submitting a concurrent program from a trigger.
ORA-20002: ORA-20026: 10322991ORA-0000: normal, successful completion
ORA-06512: at "APPS.NPX_RUN_PICKR", line 63
ORA-04088: error during execution of trigger 'APPS.NPX_RUN_PICKR'Though, this indicates normal successful completion, it does not generate any request_id. Nor, it launches the concurrent request.
Below is the trigger code. Any idea why this is happening? Thanks, R
CREATE OR REPLACE TRIGGER APPS.NPX_RUN_PICKR
AFTER INSERT
ON APPS.NPX_PICK_RELEASE

      IF l_request_id = 0

         p_message :=:New.Order_Number ||errx;
                  raise_application_error
                   (-20026, p_message);
      end if;
exception when others then
errx := sqlerrm;
raise_application_error(-20002,errx);
end;

Hello Hussein,
It is 11.5.10.2.
The line 63 represents following block
IF l_request_id = 0
      THEN                                   
         errx := sqlerrm;
         p_message :=:New.Order_Number ||errx;
                  raise_application_error
                   (-20026, p_message);
      end if;Thanks,
R
