Hi Ketsia,

You can use an Script SDK  to get the information of the documents are linked, in the following code get access to information of each document is linked:

        Protected Overrides Sub Execute()
              dim objListLinks as EntryLinkCollection
              dim strNameLinks as String
              objListLinks=  BoundEntryInfo.GetEntryLinks(true)
              for each objLinkInfo as EntryLinkInfo  in objListLinks
                    dim objDocument as DocumentInfo = Document.GetDocumentInfo (  objlinkinfo.TargetId,RASession)
                    strNameLinks=strNameLinks + objdocument.Name + ", "
              next
              SetToken("LinksInfo",strNameLinks)
        End Sub

The information for each document you want to send to a field it can be stored in a token, and then a workflow activity update the field into another document.

Attach the workflow, please rename the extension TXT with WFI ( Demo - WF Enlace SDK.wfi )

I hope you help.
