Hi,

data types just define the abstract XSD structure . but since In XI we are using XML langauge. so We need a Root element in our message. that root element is added by Messagr type.

means data type is just an abstarct structure and message type add root element to data type.

and one message type corresponds to one data type only............

Ruchika

>>>

XI 3.0 is the release in Netweaver 20004 and PI is the release in Netweaver 2004s. So from here on, in the future course XI will be known as PI. There is no major difference currently. For each release of SP in XI a parallel release is made for PI.

A comparision of the service packs in 2004 and 2004s;

in 2004 - in 2004s

SP12 & < - SP04

SP13 + 14 - SP05

SP15 - SP06

SP16 - SP07

SP17 - SP08

SP18 - SP09

Some of the features that is supposed to come in for PI is documented in this weblog - /people/udo.paltzer/blog/2007/04/26/new-sap-netweaver-process-integration-release-planned-for-2007

Hi suresh,

Data type defines the structure of your xml message.Message type is the wrapper of data type.You will be using your message type while mapping and not the data type.Its the abstraction concept used in oops
