Whilst running a report it is necessary to update a 'date printed' field in the source table. Trying to update the field from code within the report 'Detail_Format' procedure reports that I can't assign a value to this object. Is it that you can't update at all from within a report but have to run a separate update query (say) for each entry?

Use an Update query or statement via a message box on the close event of the report to confirm that the report has actually printed
