Once Liquid UI WS is installed with a valid licence, you will need to activate in SAP GUI and configure.
Activating Liquid UI
GuiXT aka Liquid UI is bundled with every release of SAP. It provides SAP users with a method to customize SAP screens and transactions without necessitating any ABAP programming. Instead, users can simply write short scripts that will customize SAP, removing unnecessary screens and simplifying the interface. Once you purchase a valid license, you can perform more advanced tasks, such as combining transactions. By default, Liquid UI is inactive. To activate Liquid UI, please do the following:
Launch SAP. Press Alt + F12 or navigate to the Customize Local Layout menu as shown in Figure 1.Figure 1: Customize Layout menu
Click the icon and the menu options appear, as shown in Figure 2.Figure 2: Customize Layout menu
Click Activate GuiXT. A checkmark will appear in front of the selected option as shown on Figure 3.Figure 3: Activate GuiXT
GuiXT is now active and you can execute your WS scripts.
