From the Case (or Item) View, under the History tab, you will see History associated with the particular Case (or Item) you have brought up if there is any. You may choose to Export the History associated with this Case (or Item) by clicking the checkbox next to the History you’re interested in Exporting, then click the Export box and choose Selected.
You may also click the Menu Customization box to customize your grid view.
On the History tab for Cases and Items, next to each History entry is a 'Details' button which will show more Details on a Case or an Item.
If you click the Details button, you will see two columns of information. The column on the left is the most current information on that Case (or Item), and the column on the right was the previous update. In addition to that, red values reflect changes that were made in the most recent update.
