      Hi,

      Refering the help link you can come to know what is external definition.

      Ususally the practical example:

      IF you have a webservice scanrio so webserver understand only the message which is in WSDL format so we need to create a WSDL meesage structure from configuration part and used that structure from expernal definition.

      Second example is in IDOC now IDOC root occurance is 0..1 but you have a file to multiple IDOC scenario that time you can change the occurance of IDOC from 0-1 to 0 to unbounded and use that IDOC strucutre from external definition.

      Third example is if you are having a std seeburger EDIFACT stucture so you can use that stucture by importing in external definition.

      Thnx,

    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

    Link is as follows
