Fastest Mapping

Hi all,

we have to post 2000 IDOC's at once to 2000 XML files. For the customer "performance" is a big issue. He wants to sent the IDOC's as fast as possible. We have allready used the "XI tuning guide" and set off the IDOC acknowledgements.

Now we are using ABAP mapping because we think this is the fastest way to do the mapping, but is this really the fastest mapping?

Now we process 2000 IDOC's in 50 minutes. Do you guys have anymore tips for tuning the performance. Please note that tuning the hardware is out of the question :).

TIA

Peter.
