http://wiki.sdn.sap.com/wiki/display/XI/Mapping+Concepts+in+SAP+XI

Having seen so many forums dealing with the mapping concepts & Techniques, Mapping errors and how to use various mapping in XI, I thought of preparing a consolidated list of all the mapping blogs which will be helpful to all the developer. I would like to thank all the contributors for providing these many blogs on the mapping concepts. 
     These links provided below will deal with various techniques that are handled in mappings.
