RfcInstallGenericServerFunctionLocate this document in the navigation structure


Installs a generic callback function of type RFC_SERVER_FUNCTION. This callback will be called by the RFC Runtime, whenever a combination of SAP System ID & function module name comes in, for which no matching callback function has been installed via RfcInstallServerFunction.

In addition to the handler function you need to provide a second callback function:


    This callback will be called to obtain a RFC_FUNCTION_DESC_HANDLE for the current function module from you. So this function either needs to return hard-coded meta data or needs to be able to perform a DDIC lookup using a valid client connection and RfcGetFunctionDesc.
