The tables described below are used by several modules in the system to manage approvals and tasks, to provide a service catalogue used by the different request types, and to track time spent on requests or tasks.

• Approvals can be incorporated into any other process table. By default, approvals are used within Contracts and Change Requests.
• Tasks may be incorporated into other tables as well. By default, they are linked to Service Requests, Projects, Assets, Support Cases, Change Requests, and External Users.
• Services define the service catalogue that is used by Service Requests, Change Requests, and Purchase Requests.
• Time entries are incorporated into several of the default tables, including service requests, problems, change requests, incidents, tasks, projects, and so on.
