Hi Pradeep,

1) Data Types - Heirarchical node structure of your source XML or target XML

2)Message Types - It uses your Data type

3)message interface - It uses your msg type

4) interface mapping - does mapping of your source msg interface to target msg interface

5)message mapping - does mapping of your source msg type to target msg type

So see you have in IR at top msg interface -> it has msg type -> it has data type.

Thanks,

Rajeev Gupta

Hi Pradeep,

Please go through the below wiki link of SAP XI glossary. This link contains information about almost all the terms used in XI. You will come to know about your query from this ref as well as you will get plenty of other information from here.:

Hi Pradeep,

A data type is a basic unit for defining the structure of the data for a message type and, as a result, for the message to be exchanged

->A data type is a basic unit for defining the structure of the data for a message type and, as a result, for the message to be exchanged.

A data type is an XML Schema Definition (XSD). This definition determines how the valid payload of a message will look. Data types in XML schema are only an abstract description of a structure that you can assign to elements in an XML schema definition. A message type or a fault message type that references a data type determines the name of the root element of a message.

2)Message Types

A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:

· More than one message interface can use the same message type. For example, an asynchronous outbound message interface and an asynchronous inbound message interface can reference the same message type because the request message does not need to be mapped.

· When defining a message mapping you can directly reference message types to map messages from an outbound interface to messages from a receiver interface.

3)message interface

You use a message interface to describe a platform-independent or programming-language-independent interface, which you want to use to exchange messages between application components using SAP Exchange Infrastructure.

4) interface mapping

Interface mappings register your mapping program for an interface pair in the Integration Repository.

5)message mapping

A message mapping refers to a mapping of messages and is supported by a graphical mapping editor. The editor enables you to design a structure mapping between any two XML structures and connect to a value mapping.
