The Audit Trail dialog box, opened by selecting the Audit Trail option in the Tools menu or the 
toolbar icon, provides a mechanism for viewing a history of changes to data. Data for any subgroup, including its traceability fields (excluding date/time), may be edited by any User with Data Edit privileges using the Edit Subgroup option in the Chart menu, or directly from the Spreadsheet.
At top in the dialog box is a list of the data editing that has occurred for the characteristics and dates specified at the bottom of the dialog box. Each row in the list contains the following information for a given instance of data editing: edit date, user who did the editing, Process Name and Characteristic Name that was edited.
The Change Detail area of the dialog box provides the specifics of the data editing for a selected instance in the above list:
Change Timestamp: the date and time the data edit occurred.
Subgroup Timestamp: the date and time that the subgroup data was initially entered into the database.
Area of Change: the data item in the database that was edited. For example, subgroup item 1 would refer to the first data value in that was collected at the time indicated by the Subgroup Timestamp (above).
Old Value: the data value before editing.
New value: the data value after editing.
Notes: Enter a comment for the selected instance by selecting the Edit Notes button. This comment is visible in the space provided. These comments are useful for indicating the circumstances of the data edit.
The following options are available for limiting the Audit Trail List. Use the Refresh button to re-populate the list.
Current Work Set Only: (Available if real-time option purchased) Select this option to limit the Audit Trail list to only those characteristics included in the current Work Set.
Current Characteristic Only: Select this option to limit the Audit Trail list to only the characteristic whose chart tab (page) is currently selected.
Last x Days Only: Select this option to limit the Audit Trail list by date. Enter from 1 to 999 days (One implies the current day).
Print: Select this button to print preview the Audit Trail. The Print Preview window contains buttons (and drop down list boxes) for zooming (enlarge and reduce) and scrolling (viewing consecutive tabs). The Back and Forward buttons allow you to view previously viewed tabs, as you might in a web browser. Selecting the Print button from the Print Preview window allows selection of the printer to use, the number of copies, which tabs will be printed, and to print the Report.
