This document will help us in understanding and achieving the following scenario by using Java Mapping


  • SAP PI receives a .csv file as an attachment.
  • The attachment needs to be read ,converted in to XML and place the XML file in the target location
  • The .csv file contains multiple records with 2 fields in each record

  Note: The above scenario can be further enhanced based on the requirement.


·        Java and PI Knowledge.
