A form is in the "Locked" status when a Participant has clicked the particular form's Lock link. When a form is locked, it can only be edited by the Participant who has locked it.
However, the “Locked” status on Workspace forms can be overridden by the following users:
The Participant who is the Workspace Owner
The EBiz POC
A Participant with the Standard AOR role
A user with the Expanded AOR role
Caution: Please consult with the user(s) who have locked the forms before completing this action. By overriding their locked forms, your action may disrupt pending updates.
