Modules and Views → System Settings → System Notifications
A notification is an automated way of being notified when specific actions occur within the application, such as when a resource submits their timesheet, when a new work item is added, updated, and so on. Some notifications–system notifications–are available to all users; other notifications–custom notifications–can be configured by each user from the Define Notifications tab in the Tools module.
You can use the System Notifications tab to manage the notifications that will be available to all of the users in your organization. System notifications are available for many events associated with the lifecycle of a work item, such as adding resource allocations or assigning risks. The full list of system notifications is available in the System Notifications tab.
You can use the Edit System Notifications dialog box to modify a system notification. System notifications are preset. System notifications are available for many events associated with the lifecycle of a work item, such as resources added, risks assigned, or timesheets due. Your administrator can enable and disable system notifications to meet the needs of the users. The administrator can also edit a system notification to make it more useful for your enterprise. The administrator uses the System Notifications tab of the System Settings module to set up system notifications.
Enabled system notifications that are also default notifications will be sent to all users in your organization regardless of their individual subscription preferences. If a default system notification is changed so that it is no longer a default system notification, all user subscriptions to that system notification will be removed.
System notifications that are enabled will be available to users in your organization from the My Notifications tab in the Tools module.
You can configure the Timesheet Due and Timesheet Overdue system notifications to be sent to recipients at a scheduled time.
