Hi Prakash,

A data type is a basic unit for defining the structure of the XML data for message type used to exchange messages with the use of SAP XI.

for more about data type plese refer:

A message type is made of a data type and describes the structure of a message on a higher level than a data type. For more about message type, refer:

>>can we use DataType with out creating msgType for MsgInterfaces?

No, because in message interface there is no option of selecting data type directly. It can understand message type only. In message type we provide a wrapper over data type, however in Message interface we define the category of message such as (Inbound, Outbound, Abstract) and Mode of message such as (Sync, Async). For more about message interface please refer:

<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/55/c5633c3a892251e10000000a114084/frameset.htm">Message Interface</a>

Hope this will clear all your doubts. If still you have any questions, please revert back.

- Data types (DTD): defines a data structure (like the Java types int, String, double etc);

- Message types (XSD): defines the message structure, based on data types or standard XML types (like a defined variable of some type: int Counter = 0; String s = "aaa"; ...)

- Message Interfaces (WSDL): defines the interface of a service that uses that message type to export/import data (like when you have a method that returns or consumes some parameters of determined types: int parseInt (String s) ).

help says,

For technical reasons, a data type is not sufficient to describe the instance of a message. In XML schema, data types are defined as abstract types that are not yet fixed to an element. You can only describe an instance of a message when you have specified a data type as an element type. Therefore, a message type defines the root element of a message.

Hi ,

DataType represents basic entities of your source and destination structures and allows nested structure.Message Type is the actual XML which holds the defined data types and gives complete XML structure.We are using Message types in message mapping.

Hi,

Data Type, Message type are Meta data... In Message interface we will mention whether it is Inbound or Out bound..Abstract..
