Mapping Techniques determines Runtime Performance

What mapping technique offers the best performance at runtime (i.e. graphical, ABAP, Java, XSLT)? I have the ability to use anyone of these techniques, but I want to ensure I am using the one that offers the best performance at runtime, not the quickest/easiest to implement at design time.

    Hi,

    In the order of performance

    1. Graphical (ease of development and fast)

    2. ABAP Mapping

    3. Custom Java Mapping

    4. XSLT (worst of all): as it does an in memory transformation, if the messages are huge, it will pound performance.

    Cheers,

    Naveen

      Hi..

      imo mapping performance does only partially depend on technique used, another important influence is the developer himself. You can develop highly performant graphical mappings, java mappings and also XSLT mappings but you have to focus on performance, know the concepts and maybe have someone else look at the mapping after it is finished 😉 I'm not sure about ABAP mapping, but i would say graphical and custom java have the same performance. XSLT is indeed slower, but there are some problems which can not be solved in graphical mapping (e.g. recursion) which can be solved rather easily in XSLT. Also SAP uses XSLT extensively in their standard content (e.g. MDM 3.0) where we have not encountered serious performance problems so far.

      best regards
