MessageObject Format
Business partners that are using PI/PO Servers send and receive MessageObjects. Each MessageObject consists of two parts, a message header and a payload.
*The payload contains the data such as a purchase order or an invoice. The structure of the payload is based on the PI/PO interface.
*The message header includes the following:
1. Sender endpoint.
2. Unique message ID for the MessageObject.
3. Receiver endpoint(Optional). Using the sender endpoint, the PI/PO Server can find the receiver endpoint using the routing relationships.
4. Quality of Service. The qualityOfService field value indicates whether the sending business partner is sending the MessageObject synchronously or asynchronously. For more information on the values for this field, see Viewing Messages.
