We “accidentally” deleted tasks from our project and lost ETC (tasks were marked like completed and ETC =0).
Is there any easy way how to revert this action? I would like to get back ETC + status of task etc.?
If you had recorded actuals against the tasks via timesheets, then the tasks will still be in the project but moved to under a "Deleted Tasks" summary task.
If you have not recorded timesheets against the plan then I think they have gone - backups are your option here (either local backups of the offline OWB or MSP plans) or restoring a database backup to a separate instance for example.
