Hi Manu,
I have placed the following code
1. against the Submit button--
if error_code=40508 then
     commit_form;
elsif :USERDELETION.CANCELLATION_USERID is not null then
do_key('COMMIT_FORM');
else null;
end if;
2. Code against the key-commit trigger in the form level--
commit_form;
DECLARE
vAlert NUMBER;
BEGIN
set_alert_property('ALERT_TO_VERIFY',ALERT_MESSAGE_TEXT, 'Your Form has successfully submitted and your Reference id is '||:USERDELETION.REF_NO);
vAlert:=SHOW_ALERT('ALERT_TO_VERIFY');
END;
3. Code against the on-error trigger in the form level--
DECLARE
vAlert NUMBER;
BEGIN
     if ERROR_CODE = 40508 then
set_alert_property('ERROR_ALERT',ALERT_MESSAGE_TEXT, 'This user deletion request has already submitted of the user named '||'"'||:USERDELETION.FULLNAME||'"');
vAlert:=SHOW_ALERT('ERROR_ALERT');
elsif
          ERROR_CODE = 40202 then
set_alert_property('ERROR_ALERT',ALERT_MESSAGE_TEXT, 'Existing userid must be filled-up !');
vAlert:=SHOW_ALERT('ERROR_ALERT');
else
               message(error_type||to_char(error_text)||': '||error_text);
end if;
END;
If there have any confusion, please ask me.
