Message Mapping ... ABAP ,XSLT and JAVA

[Former Member]

HI Friends

I have a general question ... but it will confuse me a lot ....

my question is we have four types of message mappings

1) GUI ( and UDFs)

2) ABAP

3)XSLT

4) JAVA

when we have plenty of options in GUI (and User defined functions also) to define sender 2 receiver message mapping

then what is need of JAVA,ABAP and XSLT Message Mapping and when we use these message mappings( exactly in which situation) and difference b/w them

Thanks in Advance

Thank u Ivan .. and i think ur solution is correct and but i have one more questions on UDFs and JAVA ..

basically XI is integrated with JAVA technology ... so in GUI message mapping we have UDFs (that we will be defining in java itself) ..

Now my question is what is difference b/w UDFs and JAVA message mapping

Well,

1.SAP XI is completely integrated to java tech.

2.GUI for standards message mappings generates java codes..in other words...a message mapping is a javamapping autogenerated by the tool.

3. UDF, only define a method, on other hand, with javamapping you can take the control of the all input message(input stream).

I hope this clears your ideas.

Green = recommended

Yellow = Acceptable

Red = not recommended

In my experience.

XSLT mapping: is confotable to convert to another format different to xml(when we do not have a complex logic)

Java Mapping: is to implement complex logics(but the maintainbilityis not good...you need a external tool)

ABAP mapping: I think is the best option when the you have the skills on that technology but take account that is not portable neither good for usability.

Mahaesh,

We use UDF in between source and target field in Graphical Message Mapping.

The question you have asked has been discussed several times in the past.

Just search SDN with the string "Compare mapping techniques" and you will get lots of helpful links.
