There is a separate function in TBM to cancel translation assignments. It's not enough just to change assignment status or delete it - it is usually important to notify corresponding vendors and make correct records about cancellation.

To cancel an assignment, select any assignment with Prepare, In work or Partially delivered status. Then, click Cancel assignment button on the toolbar:

The following dialog appears:

Under Notification type, you will see what type of notification is going to be sent. If assignment is in work state, then notification type will be Ongoing assignment canceled. If assignment is in preparation state and has one or multiple candidates selected, then notification type will be set to Job offer canceled. Templates for both notification types can be found on the Reference data > Message templates page.

Target action allows to select application behavior after sending notifications: set status to Canceled or delete an assignment.

Comments field allows to specify additional information included in a notification message.

Vendors table allows to select recipients of generated notifications.

When you're ready, click Send. In a few moments you will see that Sent box in the Vendors table becomes checked (or error message will appear in the Error column).

When all notifications are send, click Close button to return to assignments.
