Hi Arun,

Message Type:

A message type represents the application message exchanged between R/3 systems and R/3 and an external system. A message type characterises the data sent across systems and relates to the structure of the data called an IDOC type.

Diff. with IDOC type

An IDoc type specifies the structure of the data.

A message type specifies the meaning of the data

Diff. b/w IDOC type and IDOC

An IDoc type is the definition of a specific data structure.

An IDoc is an actual instance of data based on an IDoc type. Therefore, there can be many IDocs created from a single IDoc type.

Example:

MATMAS is the message type and MATMAS05 is IDoc type for Material Master.

Hi,

Message

It represents a specific type of document that is transmitted between two partners.

E.g. Materials, Orders, order responses, etc.

Message type

Characterizes the data being sent across the systems and relates to the structure of data.

E.g. MATMAS, ORDERS, ORDRSP etc.

Is configured through transaction WE81

IDocAn IDOC is a container that can be used to exchange data between any two processes.

IDoc Type

An IDOC type defines the structure and format of the data that is being exchanged.

Is configured through transaction WE30.

The Message type for a specific documents will be only one but Idoc type can be many.

E.g

Message Type for Material is MATMAS.

And Idoc type are MATMAS03, MATMAS05, etc.

We can link or attach any of the Idoc type of particular document type to the message type of that particular docuent as per requirement. The Idoc type will vary as per requirement but message type will be same.

Rgds,

Prakash
