Summary :
The SAP Note addresses the runtime error CALL_FUNCTION_SEND_ERROR, occurring in RFC communications when a disruption in the connection is unexpected. Key situations include asynchronous RFCs terminating before all responses are retrieved, SAP Java Connector (JCo Version 2.x) incompatibility with callbacks, and instances where an external RFC program is abruptly stopped. Solutions involve ensuring all asynchronous RFCs are completed before termination and programming the RFC destination "BACK" for callbacks correctly while checking compatibility issues detailed in related SAP Notes.
Key words :
rfc function module called, abap runtime error call_function_send_error, runtime error call_function_send_error, remote function call, sap java connector, dialog work process, pending asynchronous rfcs, asynchronous response sessions, asynchronous rfc calls, rfc server session
