If you encounter an error when trying to close a task linked to a maintenance plan, the cause depends on the type of plan the task belongs to.
Fixed-date maintenance plan
In a fixed-date plan, tasks must be closed in chronological order based on their scheduled date.
Rule: A task cannot be closed if a previous task (with an earlier scheduled date) is still active.
Example: If a task scheduled for 09/15 is still open, you cannot close the task scheduled for 10/15.
Solution: Close the oldest tasks first, in order of their scheduled dates.
Task-closure maintenance plan
In this type of plan, two tasks from the same plan cannot be closed on the same day.
Rule: The closure date of a task must be different from that of any other task already closed in the same plan.
Example: If you try to close a task with the date 03/02/2026 and another task in the same plan was already closed on that date, the system will display an error: "The recurrence date 2026-03-02 is already used".
Solution: Change the closure date or the last activity date so that it differs from the one already used in the plan.
Counter-based maintenance plan
In this type of plan, tasks are automatically generated when a counter reading reaches or exceeds a defined threshold. Closing a task does not depend on a date rule, but the task must exist before it can be closed.
If you cannot find a task to close, check that the counter reading has reached the threshold configured in the plan.
Checklist: mandatory linked task
This rule applies regardless of the plan type (and also to individual tasks), when the Require creation of a linked task option is enabled in your network settings.
Rule: When a mandatory validation step of the checklist is answered negatively (thumbs down), a linked task must be created from that step. Until it exists, neither the checklist nor the task can be closed.
Solution: Open the checklist, click Create Task below the step concerned and save the new task. You can then close the checklist and the task. To find out more, see How to complete a checklist?
