Syntax
To get: unid$ = notesDocument .UniversalID
To set: notesDocument .UniversalID = unid$
Usage
If two documents in replica databases share the same universal ID, the documents are replicas.
If you modify the UNID of an existing document, it becomes a new document.
Saving a document with the same UNID as an existing document raises lsERR_NOTES_ERROR (4000).
See @DocumentUniqueID for another way to get the Universal ID of a document and more information.
