Before transferring data with the extended functions, you must add all parameters and tables to the parameter stack.
A calling program that receives return values (RfcReceiveExt / RfcCallReceiveExt), or a called program that receives import parameters ( RfcGetData), must add import parameters to the stack with RfcAddImportParam:
