In ServiceNow, Modules are navigation elements that provide access to various parts of the platform, such as forms, lists, reports, or other application components. They are organized within Application Menus to create a structured and intuitive navigation hierarchy.

Key characteristics of Modules:

Part of Application Menus: Every module is contained within an application menu. This organization helps users navigate to different areas of the platform efficiently. For instance, the "Incident" application menu may contain modules like "Create New" or "All Incidents."

Functionality: Modules can open various elements, including forms, lists, reports, or URLs. This flexibility allows modules to direct users to specific records, filtered lists, or external resources.

Association with Tables: While many modules are associated with specific tables (e.g., a module that displays a list of incidents is associated with the "Incident" table), it's not a strict requirement. Some modules may link to external URLs or perform actions not directly tied to a table.

Access Control: Access to modules is controlled through roles. Administrators can define which user roles have visibility and access to specific modules, ensuring that users only see modules relevant to their responsibilities.

For example, a module named "Active Incidents" under the "Incident" application menu might display a list of all active incident records. Access to this module can be restricted to users with the "itil" role, ensuring that only authorized personnel can view active incidents.
