    We do mapping to transform the Source message to the target message type if these types are different for one other. The types of mapping we do are

    1.Graphical Mapping

    2.Java Mapping

    3.ABAP Mapping

    4.XSLT Mapping

    Simple answer:

    1) abap mapping it is a message mapping based on maping using ABAP class

    2) message mapping is a general term of maping mesages from one format to another

    there are a few types of message mapping:

    - Graphical mapping (in integration repository)

    - Java mapping (zip or jar file with java mapping imported to integration repository)

    - XSLT mapping (zip or jar file with xslt imported to integration repository)

    - ABAP mapping

    - ABAP XSLT mapping

    Both mappings achieve the same goal, transform from source messages to target message.

    Difference is the tools and technology, message mapping is a tool which is on Java technology and ABAP mapping is an approach to transform where we have to write the transformation program by using ABAP libraries (IXML).

    We always prefer to use tools first, simple mappings we can achieve through the graphical(message) mapping where you can use SAP standard mapping functions, for the complex mapping we should go to the external mapping programming which will be written in Java (XML parsers),ABAP (XML parsers) or XSLT.

    I hope this information helpful; let me know if you need further clarification.

      Mapping Techniques

      XI provides 3 standard ways of interface mapping between source and target.

      Graphical mapping

      Java Mapping

      XSLT Mapping

      Two more additional mapping types can be activated in XI by making changes to the exchange profile. Those two mappings are

      ABAP mapping

      XSLT mapping with ABAP Extensions

      Graphical Mapping

      Graphical mapping is a common approach followed by everyone for generating desired target structure. It involves simple drag-n-drop to correlate respective nodes (fields) from source and target structure. It hardly involves coding. (Exception - User defined functions). But sometimes with graphical mapping it is difficult to produce required output. For example ... text/html output, namespace change, sorting or grouping of records etc.

      ABAP Mapping

      A person comfortable with Object Oriented ABAP can go for ABAP mapping instead.

      Java Mapping

      Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.

      SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exaclty easy to develop either.

      XSLT Mapping

      One can also think of Java mapping as another option but it is a bit complex and required knowledge of Java. In such cases, XSLT mapping can be the best approach to meet the requirements.

      A few example cases in which an XSLT mapping can be used:-

      When the required output is other than XML like Text, Html or XHTML (html displayed as XML)

      When default namespace coming from graphical mapping is not required or is to be changed as per requirements.

      When data is to be filtered based on certain fields (considering File as source)

      When data is to be sorted based on certain field (considering File as source)

      When data is to be grouped based on certain field (considering File as source)\

      Advantages of using XSLT mapping

      XSLT program itself defines its own target structure.

      XSLT programs can be imported into SAP XI. Message mapping step can be avoided. One can directly go for interface mapping once message interfaces are created and mapping is imported.

      XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.

      File content conversion at receiver side can be avoided in case of text or html output.

      Multiple occurrences of node within tree (source XML) can be handled easily.

      XSLT can be used in combination with graphical mapping.

      Multi-mapping is also possible using xslt.

      XSLT can be used with ABAP and JAVA Extensions.

      Disadvantages of using XSLT mapping

      Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).

      Interface mapping testing does not show proper error description. So errors in XSLT programs are difficult to trace in XI but can be easily identified outside XI using browser.

      XSLT mapping requires more memory than mapping classes generated in Java.

      XSLT program become lengthier as source structure fields grows in numbers.

      XSLT program sometimes become complex to meet desired functionality.

      Some XSL functions are dependent on version of browser.

      Different types of Mappings


      Message Mapping -> Graphical Design and testing environment. Default Provided By XI. Queue based modelling allow handling or large documents. Extensible via user defined functions

      XSLT Mapping - > Based on openstandard, Portable across application platform, Extensible using user defined functions kewl but disadvantage is Memory overload while handling large documents.

      SAX -> Simple Api For XML. -> Allows you to parse through a XML document. Doesn't consume any memory. But the message can be parsed only once from top to bottom. It Has evolved by contributions made by group of ppl itz a open architecture.

      DOM -> Document Object Model -> Itz designed by W3C. Consumes Memory as the message will be loaded. Allows parsing of document in both way top down and bottom up.

      Send me your email id.Shall send you very good docs for both ABAP Mapping and message mapping.
