During a study, you may need to preserve data in its current state. In Vault EDC, you can lock data that you need to preserve. Locking data can be useful before or after data review activities. Locking data prevents any changes or any actions from occurring on the form or event until the form or event is unlocked. When an item is data locked, it is in a read-only state. Note that the audit trail is still accessible.
Note that you can’t lock Derived-type Items.
Vault shows a Locked status banner across locked Forms in the Content panel.
Users with the standard CDMS Data Manager and CDMS Lead Data Manager can perform the actions described below by default. If your study uses custom Study Roles, your role must grant the following permissions:

Ability to lock and unlock data
If your Study contains restricted data, you must have the Restricted Data Access permission to view it.
