Hi,

External Definition means you define the structure of the message outside XI and imports in the XI.

Generally, whenever we are dealing with webservices we use External definition to import the definition of message.

Here we can import *.xsd, *.wsdl and *.dto files

Real Time: Suppose u have to invoke a webservice at receiver side. Then the receiver will provide u a wsdl that incorporates the structure of the data that is accepted by the webservice. This wsdl file needs to be imported under external definition

Hi Praveen

There is a series of standard schema for describing the message structure at runtime. WSDL (Web Service Description Language), XSD (XML Schema Definition Language), or DTDs (Document Type Definitions) are often used to describe message schema. If a description of the message structure already exists in one of the above formats, you can use it in the Integration Repository by importing it as an <b>external definition</b> rather than re-entering it manually using the data type editor

for more details you can follow up sdn help
