Reference Data Objects and Version Control
If the Model repository that stores the reference data objects integrates with a version control application, you can apply version control to the objects. You can apply version control to reference tables and content sets.
You can check in and check out reference data objects from a Model repository that supports version control. You can undo a checkout, retrieve an earlier version of an object, and restore an object to an earlier version. When the reference data objects are not under version control, the Model repository locks a reference data object that you edit. Other users cannot edit a locked object that you work on. When you close the object, the Model repository releases the lock and other users can edit the object.
Note: Version control applies to the metadata that the Model repository stores for an unmanaged reference table object. Version control does not apply to the data in an unmanaged reference table. You cannot view or restore the reference data from an earlier version of an unmanaged reference table.
