There are many document management applications, which reference data in third-party-systems. If you want, for example, to archive documents from such an application, it might be useful to store that referenced data also in the archive records, in order to have independent, self-contained archive records. To achieve this, you could (1) scan your document management system with the appropriate scanner, (2) export the data from the third-party-system into a CSV file, and (3) enhance the scan run from step (1) with the data from the CSV file using the CSV & Excel scanner in enhancement mode.
