What is difference between sap r3 and r2?

Answer:
1)R/2 runs on a mainframe, R/3 runs on Client / Server 2) R/3 has a GIU (thanks to windows) where as R/2 looks more like DOS (although you can get a GUI for it) 3)R/3 has more functionality than R/2 making it the preferable choice 4) SAP will support R/3 after 2004!
