Advance thanks..

3. Which mapping is best, according to performance?

>>> the various mapping in XI are, msg. mapping, XSLT, JAVA and ABAP mappings. of course msg. mapping is rated the best in terms of performance. The rest of the mappings are still in a debate over performance:-)

Have a look at this blog and its comments to have a better idea of performance of diff. mappings - /people/udo.martens/blog/2006/08/23/comparing-performance-of-mapping-programs

Rakesh,

Message Mapping is used to transfrom your Source XML into the target XML strucutre.

Value Mapping is used for specific mapping strucutres / mapping rules. Example, Currency Conversion Mapping Rules. Instead of creating this conversion rule in every mapping program, you can create a VALUE mapping that is stored in a value mapping table and use this is your Message Mapping and thereby save up redeundant mapping logic.

Also, if the conversion rate changes, if you have used value mapping, you need to make a change only in once place and result will be reflected in every mapping. If value mapping was not used , then you would have had to make the change in all mapping prorgrams.

Take a look at this link and e learning,
