Work Orders now have a Cancelled status. It marks work as not carried out without deleting the Work Order. Your completion rate stays correct.
Before: to call off a Work Order, you deleted it or set it to Done. Both distort your metrics.
Now: you set the Work Order to Cancelled. It stays in the history but does not count as done. Your reports show what actually happened.
Work Orders created from a Maintenance Plan can no longer be deleted manually. Deleting could break the series: the next Work Order might not be created, with no visible reason why. When a scheduled job falls through, you cancel it instead. The series stays intact.
