If you identify a large scale error in your Raiser's Edge and want to make a global correction to resolve it, Audit Trail will allow you to filter your results to isolate those changes.  Once filtered, you can copy the data and paste it into an Excel file.  You can then work with the Excel file to either import a change back into the Raiser's Edge or to create a Query in the Raiser's Edge using the Constituent IDs.
