Could you please throw some light on the ABAP mapping available in SAP XI. I could find that most of the time the user defined functions are wrote using JAVA, and also understand that the entire mapping runtime in XI falls in JAVA stack. My question is Ppl with ABAP knowledge, is it possible for them to write ABAP classes for some complicated mapping conversions, node functions etc ?.
Also help to understand on what circumstances we would generally go for ABAP mappings or What are the limitations that we have with ABAP mappings.
Could you also help me to identify some blogs( if any) posted on this subject for my reference.
Thanks in advance.
