When you edit a budget value, the action is recorded in the cell history. The ability to view an audit trail in the budget workbook is particularly important to budget owners. It might be as simple as finding that a value that was entered in error and wanting to go back to see the original amount, or something more significant, such as investigating the cause of an anomaly.
Right-click a cell and click Cell History. A window displays with details about the changes that were made to the cell, including amounts, whether a formula was involved, the user’s initials and when the change was made.
You can also view the workflow history.
