    Dear Partish,


    This can be caused by several causes:


    1. You may not be authorized to debug Abap programs. Standard programs in a production system should not contain reakpoints. If you may do in the debugger, contact your system administrator, who can give you the necessary authorizations to the appropriate Authorization object.


    Please try the following notes:


    905364 - Authorizations for single step debugging of RFCs
    1471390 - Authorization check for debugging external programs


    2. This scenario can be caused when more than one person is logged in with the same username while trying to debug. With external debugging it does not work. If second person signed off, then first person during debug generates such entries in trace.


    3. It can be caused by a SAP KERNEL bug too. Further recommendation is to update your KERNEL to the latest patch.


    Best Regards,
    Barnabás

    Hello Partish,

    Please check if this is due to kernel bug.

    SAP note :

    1886841 - System core dump due to memory violation in RFC execution

    Hello,

    The return code 223 means "network read error".

    The system log (SM21) will show which component logged the issue.

    The gateway trace file is called "dev_rd".

    If it was a work process, check both the "dev_wXX" and "dev_rfcXX" files of the corresponding work process.

    Also check for any errors at the target system (if possible). If it also logs a network issue, then involve your network team.

    Regards,

    Isaías

    Thanks for all your help.

    I fixed it by unregistering DestinationDataProvider . But now I am not able to create my Http Connection with SAP server. Does anyone know about this behavior?

    • Hi!

      You are welcome! :-)

      I would say that if the original issue has been fixed, it would be better if you close this question and open a new one, for the new issue.

      If this is still related to the original issue, then we need more details about what is happening now (screenshots?).
