I am trying to import a RFC from 4.6C in Integration Builder (Design). I have Imported Software COmponent Version 4.6C in IB. In connection data for import I had put proper (case sensitive) values, group as PUBLIC. Saved & activated the configuration. After that right clicked on Imported objects - Inport RFC/IDoc - A window for entering suerid & password appears. After entering the details I get error "Unable to establish connection to R/3 system" The userid & password is correct with proper authorizations.
Can you tell me how to solve the problem? With the same way I am able to connect to 4.7 system. Is there other way to connect to 4.6C systems?
