RECALL Function (Notification)

  • Artículo

Recall a sent notification.

[Ok := ]RECALL

Return Value

Value

true if the notification was recalled; otherwise, false.

If you omit this optional return value and if the notification cannot be recalled, then a run-time error occurs that states that the notification cannot be recalled. If you include a return value, then it is assumed that you will handle any errors and no run-time error occurs, even if the notification is not recalled.

Example

The following code creates a notification and sends it if NewBalance is greater than the credit limit. If it is lower than the credit limit, it recalls the notification.

MyNotification.ID := '00000000-0000-0000-0000-000000000001';
IF NewBalance > Rec. "Credit Limit" THEN BEGIN
  MyNotification.MESSAGE := 'The customer's current balance exceeds their credit limit.';
  MyNotification.SCOPE := NOTIFICATIONSCOPE::LocalScope;
  MyNotification.ADDACTION('Fix it.', 50001, 'FixCustomerCreditLimit');
  MyNotification.SETDATA('CustomerNo.', Rec."No.");
  MyNotification.SEND;
END ELSE
  MyNotification.RECALL;
