SAP .NET Connector - tRFC Server

All,

I tried creating a RFC server using .NET connector and it works fine.

When i call the same function module in background (tRFC), I get an error

in SAP "FUNCTION NOT IMPLEMENTED raised by external server" in SM58.

I am not able to figure what is going on.

I will appreciate if anyone can help me on this issue.

    Hi,

    have you turned on tRFC on the .NET Connector designer?

    It might be also necessary to override some of the tRFC specific methods that control transaction like CheckTransaction, CommitTransaction, ConfirmTransaction and RollbackTransaction.

    Hi all,

    I get the same Error in SAP : "FUNCTION NOT IMPLEMENTED".

    I'm using the .Net Connector Class SAPIDocReceiver to receive Text-IDOCs from SAP.

    When my process crashes, for several reasons, I get this error on SAP, and I have to wait some minutes or to reboot the PC to have again a clean connection.

    I've tested my process with 3 different SAP systems (different Customers) and just in one case I get this error.

    Can someone help me to find if the problem is on SAP or in my process.

    I think that's the SAP Sys is calling an unimplemented function on the .Net Connector, or the SAP is using tRFC and not RFC, can this be true

    Best regards.

    Christophe

    • Hi Christophe,

      1. indeed the multiple objects (on multiple thread) should allow your server to scale better. If there is only one SAP server with typically one process (e.g. a batch process) that uses your RFC server, one object should be sufficient.

      2. There was a known issue in NCo 1.0 and 1.0.1 that prevented the multip connection feature from working correctly. It's fixed in version 1.0.2. Are you using it?
