Hi Manoj,
I'm very happy that you gave reply to my doubt....but in the control segment(EDI_C40 segment) from which field the data is retrieved for the checkbox in the receiver comm channel(IDOC receiver ,take receiver from payload) and moreover the result of the output of the mapping is same for both successful and failed message. my doubt is what could be the reason for the failure of the message ,both the successful and failed message structure is same in the flat file. Does anyone face this kind of issues............
