When a pending task linked to a Work Request is deleted, it can be recovered by scheduling it again from the Requests module. To review the complete procedure, see the article on management and conversion of a work request into a WO.
It is not possible to recover tasks that are not associated with a request, such as unscheduled tasks or tasks generated from work plans, as their deletion is permanent. In these cases, it will be necessary to create a new task manually.
To avoid these types of situations, it is recommended to use the event-triggered task functionality, which allows configuring the automatic generation of corrective tasks. For more details, see the article on task triggers.
