History reports allow the user to observe the audit trail of issues. The user can build a list of fields on which they wish to observe the history, and can apply filters to the report to select any issues to display on the report.
The following screenshot show the selection of the issue number, the date last modifie, the Product name, the Priority and the Status of an issue as it moved through the workflow. Of particular note is the report option to Show Changes Only. When this is chosen, report rows on the output will only display changed rows, not repeating rows that have the same data.
