PO change - ANSI X12 860

Hi all,

I have a requirement for converting EDI to IDOC with the source structure in ANSI X12 860 format (PO Change). In general, We are using Seeburger map designer for convert the EDI to XML and then do normal processing in XI, by implementing the Adapter module in the CC. But here in this case we dont have any standard structure that is supported by Seeburger for 860. How do we need to handle this PO change?

Regards,
