Outgoing Messages

"Outgoing messages" is the term used to describe messages that are initiated by our system and sent to an external system. Messages may be sent real time or near real time. The system provides two mechanisms for communicating messages to external systems.

• Outbound messages. This method allows implementers to use configurable business objects to define the message format and to use scripts to build the message. If sent near real-time the message is posted to the outbound message table waiting for MPL to poll the records, apply the XSL and route the message. If sent real time, the message dispatcher routes the message immediately.
• Notification download staging (NDS) messages. Using this method near real-time, a record is written to the NDS staging table referencing only key fields. MPL then polls the records, invokes a service to build the message, applies the XSL and routes the message. If sent real-time, no record is posted to the staging table but rather the message dispatcher routes the message immediately.

The following sections describe the outbound messages mechanism in more detail.
