SAP GUI for HTML
The SAP GUI for HTML is used in combination with the ITS technology. It runs inplace in the browser. The contents are generated by the Internet Transaction Server (ITS). The SAP GUI for HTML need not be installed separately on the client computers.

You have to define the corresponding Web entry points in the system landscape.
These are used to compute the final URL used to access services on the ITS
server.
For more information see System Landscape and Creating System Objects.
The Internet Transaction Server (ITS) is also used as the server for MiniApps and Internet Application Components (IACs) of the mySAP Workplace.
