    the function module is calling network layer to get back the hostname from IP.

    If this call returns error it means the IP address can not be resolved on OS level to hostname.

    Please check with the server admin if the IP can be resolved on os level.

    Best regards,

    • Hi Trevor,

      You can do test with report: RSBDCOS0, if the user the SAP System is using has the same results.


      You can also try to debug the code, to see the exact error returned from the kernel call.

      Best regards,
