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: 

Pro: 

- 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.

Cons: 

- 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: 

Pro: 

- native high performance

Cons:

- 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

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.
