SAP: Is there a cross platform HTML web based client?

I'm aware of the client in the form of a Windows application (which uses SAP's own interface standa开发者_如何学Pythonrds) but is there a HTML based client that one can freely download with the same functionality?

If you're referring to SAP GUI, there is a Java version. I've used it under both Linux and Windows.

All of the different SAP client platforms are detailed on SAP's SDN site: http://www.sdn.sap.com/irj/sdn/sap-gui

You can see there is a GUI for Windows, and for Java (e.g. for Linux or Mac users).

There is also the SAP GUI for HTML (aka ITS webgui) which is probably what you are after. This allows access via a web browser, without needing to install a specific client application. It does require some setup on the SAP server however.

Isn't nearly all the functionality available via the webgui?
