Introduction and how to configure SAP Web GUI

To eliminate the extensive support of SAP GUI maintenance and upgrade on user PCs, the SAP Web GUI would provide an alternative solution to avoid all the support hassle and attractive benefit of zero installation.

A) Introduction on the SAP GUI family:

1) Web / HTML GUI: 
- Suitable for users who work with SAP transactions but don't require the performance of a native GUI
- Runs within standard browsers on Windows, Linux, MacOSX, iPad or Android browsers.
- Not getting the performance of an natively running software
- User may encounter usability limitations that caused by the browser framework
- Requires ITS in your SAP landscape to render pages

2) Windows / Java GUI: 
- native high performance
- Requires local installation of the solution.
Requires Java Plug-In on the client side (Java GUI)
- Have to worry about the software installations, upgrades, etc

B) Steps to setup the SAP WEB GUI

1) Verify the ICM configuration parameters. Execute TCODE: SMICM

2) Click "Goto" -> "Parameters" -> "Display"

3) Ensure the parameter: icm/server_port_0 = HTTP,PORT=<Desired port ex:8000>, ........

4)  Ensure the parameter: icm/host_name_full = <Full Qualified Domain Name/FQN>

4) Execute TCODE: SICF, click the "execute" button

5) Select the following node and active the services:
- /default_host/sap/bc/gui/sap/its/webgui
- /default_host/sap/public/bc/ur
- /default_host/sap/public/bc/its/mimes

Right click the selected node and click "Activate Service"

6) Click "Yes"

7) Execute TCODE: SIAC_PUBLISH_ALL_INTERNAL (wait few minutes to activate the publishing services)

 8) The progress will be shown in the status bar

9) Once the progress complete, a information screen will be shown.

10) Login with one of the following URL from the web browser
- http://<IP>:8000/sap/bc/gui/sap/its/webgui
- http://<FQN>:8000/sap/bc/gui/sap/its/webgui

 11) The login splash screen
 12) The SAP Web GUI main menu

13) Sample login screen with iPad

C) Troubleshoot:

1) Problem: The required icm parameters not found
    Solution: Execute TCODE: RZ10 to add the parameter to the profile 

2) Problem: How to check the FQN 
    Solution: View the "C:\Windows\System32\Drivers\etc\hosts" file 
                  (depends on windows configuration, some might not be available and could be added manually)

3) Problem: Error "Session not found" when executing TCODE in SAP Web GUI after login

Solution: Execute TCODE: SICF_SESSIONS and select the client to be access by Web GUI

Double click the state to activate it and retry the login again.

4) Problem: How to ensure the Web login connection details
    Solution: By using the sapmmc (windows), select the connections icon under the ICM for more details

D) Conclusion 
That all for the configuration and in the end, it's all depends on the environment and on the type of users whether to use pure native GUI or Web GUI or even mixture of it.


  1. Thanks a lot for this post! It's very useful

  2. Great blog.
    Were you able to click on the SAP menu entries or only use the t-code entry box?

    1. It depends on the browser compatibility .. certain node are not able to expand at all, entering tcode on the textbox is ok..

  3. Great Blog!
    I am facing a issue with tcode SPRO->SAP Reference IMG and SUIM. we got dump regarding "Illegal_Event_Combination" with Web GUI.
    Please help me with solution.
    Thanks in advance!

    1. Did you try this solution, SAP note: 1834690

    2. This note for GUI for Windows(SAP Logon). Please guide me how can I apply this note in GUI for HTML.

  4. I have no experience on this probably you can try with the SAP Global support and share with us on the resolution..

  5. HI Eddie,
    Thanks for your great blog and helpful posting ! We managed to configure webgui.
    We are finally able to login and transact in SAP using Internet Exporer.
    We are also managed to login to SAP using Safari in an iPad/iPhone. However, SAP (webgui) is not responding to any tcode entered in the command prompt or double-click of a menu in SAP Easy Access screen.
    Have you encountered a similar issue for WebGui in iPad, what setting that may have caused this behaviour? Thanks, LLC

    1. I have similar issue, yet to try with other browser ....

  6. Hi Eddie did you ever get it to actually work on the ipad safari browser? I can get it to work on a mac with safari but I can only logon with ipad but stops at "get computer name" and I don't get any SAP menus

    1. Probably with other browser is it ok? I only explore with entering tcode to launch the program instead depending on the menu which some time having compatibility issue...
