I have read the weblog of Roberto Negro concerning the possibility of adding fields to the communication structure of an extractor.
In his article he talks about MCVBAK and so on and refers to enhancements MC10001, MC50001, MC60001.
I am trying to do the same with 2LIS_02_ITM.
The communication structures are MCEKKO and MCKPO.
Can someone explain how to proceed in order to locate the approporiate user exit ?
