1. Click Import Document Links from the Actions menu:
   
   
   
   NOTE: If Import Document Links does not appear in the dropdown list, it means the Vault does not allow users to use this functionality. Open a ticket with the Global Service Center for more information.

2. The Import from selected document dialogue opens. Select the target document to import the document links from:
   
   
   
   
3. Click Continue to confirm the action:
   
   

All references from the selected document appear in the Linked Documents section.

Annotate and Edit Relationships permission is needed in order to manually Link Imported References to the content of the current document.
