System settings

The System Settings modal window is accessible (in UI16) by clicking on the settings gear icon in the Banner Frame. When you are logged in as System Administrator or a delegated developer, you will have the following settings available:

• General: Here you can change your time zone, view a printable version of the content frame, and change a few accessibility-related settings.
• Theme: Allows you to select and change your UI's theme color.
• Lists: Here you can change settings related to a list of records module pages:
  • Wrap longer text in list columns: If enabled, breaks long text into lines in order to minimize horizontal scrolling in the list of records module pages.
• Forms: This tab allows you to change how your Form UI loads and work:
  • Tabbed forms: If enabled, all related lists and sections on the form show up in tabs in all forms.
  • Related list loading: Allows changing how related lists load in the form. We can choose to load related lists With the Form, After the Form, or On-Demand.
• Notifications: This tab allows users to enable or disable mobile, desktop (web), e-mail, and audio notifications.
• Developer: This tab is only available to users with an admin role or a delegated developer. This tab allows developers to select their current Application and working Update Set. The following settings are available under the Developer tab:
• Application picker drop-down: Allows selecting an application scope and marking it as active. This prevents developers from making modifications to any other application other than the one that is currently selected. One ServiceNow instance can have more than one application scope defined but a user can work only on one of the scopes at any given time.
• Show application picker in header: If enabled, shows application picker drop-down in the banner frame. We will keep this setting enabled for the rest of our chapters.
• Update Set picker drop-down: Allows selecting an Update Set and marking it as active. Update Sets are like containers, which record changes to the selected Application scope and allows easy migration of changes to other instances and rollbacks. One application scope can have more than one Update Sets defined but only one marked as active.
• Show update set picker in header: If enabled, shows the Update Set picker drop-down in the banner frame. Keep it enabled for the rest of our chapters.
• JavaScript Log and Field Watcher: If enabled, shows the JavaScript Log and Field Watcher frame within the Content Frame.

After enabling Show Application and the Update Set picker in the header settings, both drop-down fields will appear in the banner frame, which will enable us to quickly change the active Application scope and Update Set:

The ServiceNow platform comes with a default Application scope named Global and a default Update Set under the global application scope named Default [Global]. We will be covering how the Application scope and the Update Set works in detail later in the book. One key thing to remember is that the Application scope is different to application menu links, which are visible in the left navigator and explained here:
