TrueLog Explorer offers two high-level SAPGUI functions: 
               
               
 
                  
                  -  
                     SapGuiActiveSetWindow – These are top-level API nodes that indicate the generation of a new GUI window. All actions taken on windows are grouped
                     below a 
                     SapGuiActiveSetWindow function. 
                     
                  
  
                  
                  -  
                     SapGuiRoundTrip – These are virtual nodes; there are in fact no API calls called 
                     SapGuiRoundTrip that are sent to the server. These nodes are used to group all client-side actions that occur in the course of a server round-trip.
                     Both the before and after states of round-trips can be viewed. Multiple round-trip nodes may be included under each 
                     SapGuiSetActiveWindow node.
