Universally Unique Identifier (UUID)

UUID is a unique identifier that can be used to correlate request and response messages. Each request from SAP contains a unique identifier in the MessageHeader/UUID element. When ISAIM returns a response to SAP, the response message references the same unique identifier in the MessageHeader/ReferenceUUID element.

Similarly, when ISAIM sends an unsolicited message to SAP, the message contains a unique identifier in the MessageHeader/UUID element. When SAP sends a confirmation message back to ISAIM, the message references the same unique identifier in the MessageHeader/ReferenceUUID element.
