As per the requirement In the Requisition page when the Wanted by Date is greater than the System date and time then the message text in the notification message need’s to be sent to the mail id’s present in the distribution list. This can be achieved by the XML Business Rule with the <Perform_send_to_monitor> .So I require some references from any one about this requirement.
Attached images below for reference.
Thanks,
