Using the item set history

You can view a detailed audit trail for each of your subject’s item sets in their item set history. The item set history provides documentary evidence of all events, activities, and actors that have affected the item set since its creation.

This article explains how to use the item set history.

1. Go to your item set’s Edit screen

Select an item set in your subject to open it and go to the Edit screen.

2. Open the item set history

Select Item History to open the item set’s history.

3. View the item set history

The item set history data grid is arranged in the following columns:

Column	Description
Version	Lists all historical item versions. Items change version when changes are saved. Each version has its own row in the item history grid. Items can have major versions (whole integers like `1`, `2`, and `3`) and minor versions (non-integer decimals like `1.1`, `1.2`, and `1.3`). A new major item version is created every time there are saved changes to the item owner or workflow status. Any changes made to live items create a new major version.
Last Edited by	Details the user who made the changes to the item version.
Last Edited at	Details the date and time at which changes were made to the item version.
Changes	Details the type of change made to the item version. If the item version has many changes, the Changes cell displays “Multiple changes made”. To view a list of each change, select the expander in the Version column.
Details	Gives specific information about what was changed in the item version. For more information, see ‘Using the Details key’ later in this article. NOTE: Users without the Comment Manager permission are unable to read to private comments in the Details column.
