SIU^S15
SIU/ACK - Notification of appointment cancellation
Unsolicited transactions from filler applications are the messages and trigger events used between filler applications and auxiliary applications. Transactions are initiated by the filler application, using the SIU message to notify auxiliary applications of modifications in a filler application's schedule(s). The auxiliary application responds to these notifications, using the ACK message, either to acknowledge receipt of the transaction, or to signal that an interfacing error of some kind has occurred.
This set of trigger events is also used to notify applications fulfilling the placer application role of changes in the filler application's schedule(s), if the application is configured to accept these messages and trigger events as an auxiliary application would. As the discussion of application roles has indicated above, any one application can have more than one application role. If it is important that the application acting in the placer application role in your messaging environment be notified of unsolicited changes to a filler application's schedule(s), then it must also support the role of an auxiliary application.
