  • Hi @kiran kiran,

    Hi Frederick,

    I am getting the below error when trying to post the data in SAP from Postman.


    <TITLE>500 SAP Internal Server Error</TITLE>
    <H1>500 SAP Internal Server Error</H1>
    ERROR: Internal server error ... unable to determine HTTP calling object (termination: ABORT_MESSAGE_STATE)

    One more question why we are not able to see the JSON payload in PO which has been processed from source(REST)? As this is pass through scenario and as there is no mapping, we need to see the payload in PO which is missing.

    Thanks & Regards,


  • Hi Kiran,

    You are not able to see the JSON payload means, the logging might have not enabled properly.

    In REST sender communication channel, make sure the check box "Log JSON Message" is selected.

    Also, in the ICO Advanced Settings tab, turn on scenario specific logging/staging for all the required steps to see the payload.
