After you configure SmartPlant Foundation documents with tags as a document source, you can change the interface of the tag class and the relationship used by updating Tags Query Interface and Tag Documents RelDefinitions in SPC System Options.
After you add a component to a work package, you can search for documents linked to the tags with the same name as the attached components. You can then attach the documents to a work package in the Available Files dialog box of an IWP. By default, all documents and classifications are displayed; however, you can narrow this list by document classification, based on the package discipline and purpose by modifying the Document Lookup Config file. For example, the default value for SmartPlant Fusion is Fusion Document Lookup.xlsx workbook.
