HI,

Message Type indicates How to Know what the data Means

Data Exchanged by IDOC and EDI is known as Messages

Message of same kind belong to the same message type

Message types are stored in table EDMSG

Hi paresh,

The custom idoc which we create can be used in many places ...The message type defines the application of idoc

Hi Paresh.

We generally use standard message types in SAP, but when we want customization or our own messages. This is when we create our own Message types in WE81.

Good Luck & Regards.

hi

good

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.
