RECALL Function (Notification)
Recall a sent notification.
[Ok := ]RECALL
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.
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;
