How to ask user to discard or save changes in a custom form

Question

Hi
let's take emp, dept... whenever user is updating DNAME if it has been assigned to more than one employee.... the form should show a warning message and should ask user to SAVE or DISCARD option?
How can you do that. is there any built-in function or trigger to pop-up SAVE or DISCARD window option?
Thanks

Hi
Key-next-item trigger is not working. my block is a MULTI-RECORD block. i wrote below code in PRE-UPDATE trigger, it's working when i select SAVE and not working when i select DISCARD option(alert has two buttons SAVE and DISCARD)
DECLARE
lv_assigned_more_prd NUMBER;
alert_button NUMBER;
e_assigned_more_prd EXCEPTION;
PRAGMA EXCEPTION_INIT ( e_assigned_more_prd, -100501);
BEGIN      
IF :System.record_status = 'CHANGED'      THEN
SELECT count(*)
INTO lv_assigned_more_prd
FROM xxgl.xxgl_sdroy_product_je_rules je
WHERE je.je_rule_id = :XXGL_SDROY_JE_RULES_V.je_rule_id;
IF lv_assigned_more_prd > 1 THEN      
     alert_button := Show_Alert('ALERT001');
     IF alert_button = ALERT_BUTTON2 THEN
     RAISE e_assigned_more_prd;      
END IF;           
END IF;     
END IF;
EXCEPTION
WHEN e_assigned_more_prd THEN          
raise form_trigger_failure;
WHEN OTHERS THEN
fnd_message.set_string(' Oracle Error -- '||SQLERRM);
fnd_message.error;
raise form_trigger_failure;
END;
