RFC_COMMUNICATION_FAILURE if trying to confirm transaction trfc client

[Former Member]

Hi,

I recently updated our c++ trfc client to the SAP Netweaver 7.20 SDK.

But there is a strange issue:

I'm getting RFC_COMMUNICATION_FAILURE if I am trying to confirm my transaction after filling and committing it to my SAP Backend.

Sometimes it works for transactional rfcs if I am closing and reopening the transaction.

The strange behaviour is: If am doing the same in Visual Studio in my debugger, the whole process completes successful.

Any ideas?

Regards,

Ben

Hi Ben,

Got any dump in ST22 for the RFC? Can it be shared?

Thanks,

Hi Henry,

unfortunately not.

But I have a trc file from my client machine.

I will commit this one.

The corresponding SAP Errormessage is:

RfcLastError (1) :

Result-Text: | RFC_COMMUNICATION_FAILURE|

message  : |

LOCATION    CPIC (TCP/IP) on local host vsl501810 with Unicode

ERROR      no conversation found with id 51384437

]

Context:

                  rc = 1

                rfc = IDOC_INBOUND_ASYNCHRONOUS

            saperror = RfcLastError (1) : Result-Text: | RFC_COMMUNICATION_FAILURE| message  : |  LOCATION    CPIC (TCP/IP) on local host vsl501810 with Unicode ERROR      no conversation found with id 51384437 TIME        Mon Sep 14 13:09:09 2015 RELEASE    720 COMPONENT  CPIC (TCP/IP) with Unicode VERSION    3 RC          473 MODULE      r3cpic.c LINE        9217 COUNTER    14 | key      : | RFC_COMMUNICATION_FAILURE|

                tid = XOV6/2AAAD94MSP7_5AAAAAB

It seems for me as the connection is lost during the transaction...

Thanks.

Regards,

Ben

--Edit:

Just fixed the Error:

In the data i tried to transmit, the docnum fields in edi_dc40 and edi_dd40 were set in my programm-code.

So SAP is internally cancelling the transaction.

After leaving the fields empty, everything worked fine for me!
