External 'C' function module not available during TCP/IP RFC call

[Former Member]

Hi,

We have set up a TCP/IP connection from SAP to an HP-UX executable program and had the program registered. The RFC works when doing a test connection in SM59. However, when we do the call from an ABAP program using an external function module called 'SOCKRFC1' that should be available in the RFC call, we are getting an error message "Function SOCKRFC1 is not available". The SockGW.c file that was used to compile the SockGW.out file has a call to the SAP RFC function InstallFunction. Does anyone know why this 'SOCKRFC1' function would still be unknown to SAP?

Thanks,

Stephen

Hi,

Did you create a stub abap module function called SOCKRFC1 ?
