User Locked Records (claimed)
Prior to the 1.72 release users had to manually click on the “claim” action to lock a production record while working on it. As of 1.72, the records are automatically locked by the user as soon as they select the Document Production action.
The original user that locked a record can always edit or release a record they locked.
Administrator level users can unlock or edit any production record, regardless of who locked the record.
