Creating a History Report
The History report is not part of a default report. Therefore, you must select Insert Report to add a history worksheet to a Report Definition File (RDF) (see How to …: Creating and Using Report Tables 
Adding and/or Renaming a Worksheet).
By default, the worksheet shows the history of the current sample. Select Table Properties on the context menu to open the History Report Properties dialog box and change the settings:
On the History Objects tab page, select the object for which you want to display history entries.
On the Time Restrictions tab page, specify the time when the history entries to be displayed must have been made.
On the Operations tab page, determine the changes to be displayed.
On the Users tab page, determine the user(s) whose changes are displayed.
On the Sorting tab page, define the sorting order for the history entries.
A special layout mode is provided for the history report. Select the Layout Mode on the Layout tab page. However, this is only possible if detail columns are available. If detail columns exist, select the Design template mode to display a shortened history report (this simplifies the layout definition).
