Link To a Master Document
                                            Linking to a master document can be useful when you import a new document into a project folder from outside the vault. In this scenario, the document should have become a project copy of a master document that resides in the vault, but it was not copied from the master document using a managed change command. Linking the new project copy will create a reference to the master document that you select and will create a revision of the master document when the linked copy is released.
The command is unavailable if:
- 
                                                        
You select the two documents in the reverse order.
 - 
                                                        
One of the documents is under change.
 - 
                                                        
The imported document is already linked to a master document.
 - 
                                                        
The imported document is not in a project folder.
 - 
                                                        
The master document is not in a higher folder level than the project folder.
 - 
                                                        
The master document already has a project copy.
