FND_MESSAGE.SET_NAME

Retrieves your message from Message Dictionary and sets it on the message stack. You call FND_MESSAGE.SET_NAME once for each message you use in your client-side PL/SQL procedure. You must call FND_MESSAGE.SET_NAME before you call FND_MESSAGE.SET_TOKEN.
Example 1

/* Display a warning,asking OK/Cancel question */
FND_MESSAGE.SET_NAME ('FND','WANT_TO_CONTINUE');
FND_MESSAGE.SET_TOKEN ('PROCEDURE','Compiling this flexfield');
if (FND_MESSAGE.WARN) then
  /* User selected OK,so add appropriate logic ... */ 

FND_MESSAGE.WARN

Example:

/* Display a warning,'WANT TO CONTINUE');
FND_MESSAGE.SET_TOKEN ('PROCEDURE','Compiling this flexfield');
IF (FND_MESSAGE.WARN) THEN
  /* User selected OK,so add appropriate logic ... */
ELSE
  /* User selected Cancel,so add appropriate logic ... */
END IF;

FND_MESSAGE.ERROR

Example:

/* Display an error message with a translated token */
FND_MESSAGE.SET_NAME ('FND','FLEX_COMPILE_ERROR');
FND_MESSAGE.SET_TOKEN ('PROCEDURE','TRANS_PROC_NAME',TRUE);
FND_MESSAGE.ERROR;
  /* Then either raise FORM_TRIGGER_FAILURE,or exit  
     routine*/   

FND_MESSAGE.SHOW

Example

/* Show an informational message */
FND_MESSAGE.SET_NAME ('FND','COMPILE_CANCELLED');
FND_MESSAGE.SHOW;   

FND_MESSAGE.QUESTION

Example 1

/* Display a message with two buttons in a modal window */
FND_MESSAGE.SET_NAME('INV','MY_PRINT_MESSAGE');
FND_MESSAGE.SET_TOKEN('PRINTER','hqunx138');
FND_MESSAGE.QUESTION('PRINT-BUTTON');
  /* If 'PRINT-BUTTON' is defined with the value “Print",the user sees two buttons: “Print",and “Cancel".  */  
       
Example 2

/* Display a message with three buttons in a modal window.
   Use the Caution icon for the window. */

FND_MESSAGE.SET_NAME('FND','DELETE_EVERYTHING');
FND_MESSAGE.QUESTION('DELETE',NULL,'CANCEL',1,3,'caution');

/* Display a message with two buttons in a modal window.
   "Yes" and "No" */

FND_MESSAGE.SET_NAME('FND','REALLY');
FND_MESSAGE.QUESTION('YES','NO',NULL);

FND_MESSAGE.DEBUG

 /* as the last part of an item handler */
       ELSE 
          fnd_message.debug('Invalid event passed to
              ORDER.ITEM_NAME: ' || EVENT); 
       END IF;
