"CPIC-CALL: 'ThCMSEND' : cmRc=18 thRc=0#Statistics not active " ABAP dump


I used a external RFC client and call function modules on SAP system via RFC connection to retrieve data from SAP, sometimes, I got a short dump with the short text CALL_FUNCTION_SEND_ERROR. The dump goes on to say "CPIC-CALL: 'ThCMSEND' : cmRc=18 thRc=0#Statistics not active " Status of connection.... "CODE=CM_DEALLOCATED_NORMAL CM_SEND_RECEIVED


Internal error code.... "RFC_IO5"

I searched sdn but the only two hits are very old and dont seem to offer a solution. Does anyone know the cause of this one?

Best regards

    Hi friend,

    As you told it is external RFC which is a non-SAP system

    they need to register with SAP system

    go to SM59 and in CPIC connections check for your destination and double click on that and give test connection ,

    hope you will get teh same error there as well, it seems that they haven't registered

    ask your basis person to check the same.

      Thks for your suggestions, but I have a question here, most of the SAP system work except one generate the ABAP dump. Our function modules don't need any configuration you metioned and it works on most of the SAP systems, so from my point of view, it has nothig with destination settings ,do you think so?

    • Hello,

      I understand this is a 5 year old thread...

      But I am seeing this situation randomly as well in our production ECC system, and this thread matches exactly.

      Our scenario is this: we have an application that uses an RFC connection to export system statistic information (STAD/ST05) to an external database for historical purposes.

      The application calls the RFC approximately every 5 min 24/7/366 and only gets the message and dumps (CPIC-CALL: 'ThCMSEND' : cmRc=18 thRc=0#Statistics not active) about 1% of the time.

      Please let me know what your resolution was.

    • Carlos,

      For us the issue was connected to many, many, GUI sessions not being released from the gateways after logoff.  This was causing an issue where the communication was timing out waiting for an available session.

      In our case, using tcode SM04 on each ECC application server, we could see extremely old non-active RFC sessions. After removing those session that were inactive for at least 24hrs (painstakingly, one-by-one) we saw immediate relief and the new RFC's stopped failing.

      I'm pretty sure it's a kernel issue, but we only saw it in production where the load is great enough for it to surface.

      Not really a resolution, but I hope that helps you find yours.


      PS: You can easily see if this is part of your symptom by using tcode SM51 ==> Goto ==> User (click)

      then Goto ==> System Wide List

      and sort the output by "dialog time"

      (My references are on  ECC 7.40 EHP7)
