By design, an MRO object is locked if its parent MRO work package is confirmed. This type of locking is applied recursively to all child MRO objects.
=== Locked by [[MRO_Objects_(Client)#Sequential_Task|sequence]] ===
An MRO task can also be locked if it belongs to a sequential list of tasks that must be completed in order, in this case all tasks but the current one ones that are currently active in the sequence are locked.
== Locking through access rights ==
