Hi Gayathri,
I guess you need to be clear with the requirement.
- If your requirement is just to send the file as an attachment to the inbound proxy then you can follow the java mapping approach.
- If it is to trigger the data from the file to the ABAP proxy, then you need to convert the data in the file into XML using FCC and then pass it to the proxy. You can use the same MT, DT in the outbound and inbound SI without any OM and MM.
