hi this is seshagiri.
i have doubt abt proxies. when u created ABAP server proxy,objects were generated.
1. ABAP interface
2.structure for data type
3. structure for msg type
WAT IS THE DIFFERENCE BETWEEN DATATYPE STRUCT AND MSG TYPE STRUCT.
AND ONE MORE THING IS PROXIES ARE RUNNING ON WHICH ENGINE
Hey
Data type structure is the most basic structure which u create in accordance to your sender/receiver data format,Message type structure is actually a wrap over the Data type st. and actually it confirms to WSDL standard.
ABAP proxies run ABAP engine.
thanx

Giri,
3. structure for msg type --- It is just like our message type in XI
2.structure for data type --- It is the datatype what we create normally in XI
Hope this is where you have confused. Also proxies run directly on Integration engine so they can handle very high load also efficiently.

Hi,
To see the deff between DT and MT
A message type comprises a data type that describes the structure of a message
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.
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.
A message type does not define the direction of the message exchange
