Analyzing Interface Objects in the ESR: Message Types

Objective

After completing this lesson, you will be able to create message types

Message Types

The message type describes the structure of a message that SAP Process Integration (PI) sends or receives and determines the root element of the message. The message type references a single and complex data type and can be used for both outbound and inbound service interfaces.

An eXtensible Markup Language Schema Definition (XSD) version of the message type is provided in the Enterprise Services Repository (ESR) for the export of the interface.
