.NET Connector 3.0 Error: "client with wrong appc header version rejected"

Former Member

Hi Folks,

I am in the process of upgrading our software to use the SAP .NET Connector 3.0 (from the .NET Connector 1.0). All of the function calls are executed successfully, however, periodically we get the following error that is repeated 4 times:

Unhandled Exception: SAP.Middleware.Connector.RfcCommunicationException:

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

ERROR       client with wrong appc header version rejected

TIME        Fri Aug 17 09:40:35 2012

RELEASE     720

COMPONENT   CPIC (TCP/IP) with Unicode

VERSION     3

RC          246

MODULE      r3cpic.c

LINE        8554

DETAIL      client version 6, gateway version 120 (xxx.xx.x.xx/3301)

COUNTER     2

The stack trace for this error is:

    at SAP.Middleware.Connector.CpicConnection.CpicReceive(Int32 timeout)

Immediately after that error another error is thrown 4 times:

destination x failed when calling RFC_METADATA_GET -- see log for details

The stack trace for this error is:

at SAP.Middleware.Connector.RfcRepository.Execute(RfcFunction function)

The error does not seem to be related to any particular function call but, rather, it occurs periodically (approx. 20-30 minutes at present) for any of them.

The version of the DLLs that I am using are as follows:

sapnco.dll               3.0.2.0

sapnco_utils.dll        3.0.2.0

I am afraid that I don't really know my way around the new .NET Connector yet and would be very grateful if anyone had any thoughts, clues or suggestions.

Yours,

Is no-one in SAP support aware of this issue? It seems that others have asked this question but with no progress.

This was fixed with Patch level 9 (3.0.9).  The latest version is 3.0.10 -- (3.0.9 introduced bugs and SAP pulled that version.)

Thanks thats great.. I will try installing the new version - hope that 3.0.9 helps.

Also do you know where i can find the release notes for this version, to verify if other issues have been addressed.

Thanks a lot Case Ahr, It worked.

Version 3.0.10 solved the problem. I'm not having dropped downloads or caching the failed connections issue.
