Details About Data Protection
You cannot modify the data in a checked-out file if the corresponding Contenta object could not be locked.
Note, however, it is possible for chapter objects to be unprotected while their parent book object is protected.
All locked objects are exported read-only. Do not change a file’s read-only status. If you change the file’s read-only status then make modifications to the file, know that the file cannot be checked-in to the Contenta database.
