Using schedules and calendars

Specific applications within the ServiceNow AI Platform generate graphical calendar displays based on schedule pages.

These schedule pages appear in daily, weekly, or monthly views. Currently, the applications using schedule pages include:

• Project Management
• Maintenance Schedules
• Group On-Call Rotation
• Field Service Management

Schedule pages are records that contain the scripts that determine the functionality of the graphical display.

• Because of the heavy degree of scripting involved in a schedule page, you should, for most instances, use the default schedule pages in the base platform.
• The schedule page uses a URL with a series of parameters attached to generate the graphical display.
• A schedule page controls calendar content (cmn_schedule_page) record.

To access Schedule Pages, navigate to System Scheduler > Schedules > Schedule Pages. The Schedule Pages form provides the following fields:

Field	Field Type	Description
Name	String	General name used to identity the current schedule page.
Schedule type	String	Schedule type is a string that is used to uniquely identity the schedule page via the "sysparm_page_schedule_type" URI parameter. For example, a schedule page could be accessed as follows: /show_schedule_page.do?sysparm_page_schedule_type=gantt_chart&sysparm_timeline_task_id=d530bf907f0000015ce594fd929cf6a4 Alternatively, you can access the schedule page can by setting the "sysparm_page_sys_id" URI parameter to the unique 32 character hexadecimal system identifier of the schedule page.

It then injects it into the display page prior to the rest of the calendar. It can be used to pass in variables from the server and define extra fields are necessary.
Client script	String	The client script is a scriptable section that allows for configuring options of the schedule page display. The API is different depending on the schedule page view type.
