What is the Technical Reason for Creating Message Type

[former_member331856]

Hi,

Is there any particular reason to use Message Type. Already we are defining Data Type. Please give me some detailed explanations.

Thanks in Advance.

Thanks & Regards,

Hi Giri,

SAP telling below reason why we are creating message type

"A message type comprises a data type that describes the structure of a message. For technical reasons, a data type alone is not sufficient to describe the instance of a message: Data types are defined in XML Schema as abstract types that are not yet tied 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"

Addition to above message type forms/creates the exact root tag send by the sender application system...

by this it allows to you to reuse the datatype for many applications if the structure is same..only thing is need to create the message type with exact root tag(i.e structure expected from the sender..)

Data type need not have any sub elements in it. Only a message type has the constraint to have a root element and any sub elements.

Data type just defines the structure....however Message type contains the actual payload (i.e. structure + data)
