Hi!
Thanks for the response.
The iNum column is unique within a report, but it appears to reset itself and repeat from report to report, thereby preventing the table from setting that column as a primary key. We may be able to circumvent this by creating a database VIEW that retrieves only the latest report and creates a concatenated column with unique values. Nevertheless there are maintenance considerations with this. We may consider it in the future.
Thanks for the correspondence. We will definitely keep up with future versions of Aida64.
