Oracle 12c AFTER INSERT OR UPDATE TRIGGER

Question

I Have a following trigger, which updates but and rolling back automatically, I'm not finding what is the cause, kindly help.

FYI: updating table UDF_DATA has a foreign key reference to CCEX.CUSTOMER triggering table.

CREATE OR REPLACE TRIGGER TR_CUSTOMER_PM
AFTER INSERT OR UPDATE ON CCEX.CUSTOMER FOR EACH ROW
DECLARE
  i_subscriber_id     Number :=3080;
  user_xcep EXCEPTION;
  PRAGMA EXCEPTION_INIT( user_xcep, -20001 );
  pragma autonomous_transaction;
  i_syscode ccex.customer.cust_system_code%type;
BEGIN
  IF  :new.cust_account_number like 'TID%' THEN

    i_syscode:=  :new.cust_system_code;
    update udf_data set value = 'Term'
    where subscriber_id = i_subscriber_id
    and cust_system_code = i_syscode
    and entity_id = '1488_OTA'
    and udf_id = '3994_OTA'
    and name = 'Primary Manager';
  END IF;
EXCEPTION
  when others then
    raise user_xcep;
END;
/

Answer 1

Since the trigger is in autonomous_transaction mode, it should close the transaction.

Please add commit just before the exception line.
