Updating records safely
Update several records simultaneously without using scripts by creating and executing a batch update job. For example, you might want to update the Assigned to value for multiple incidents on a test instance without running a script.
To update multiple records safely, create an update job, and then preview the number of affected records before you schedule or execute the job. For more information, see Mark records for updating.
If you must restore the updated records to their previous state, use the rollback option in the update job. For more information, see Rollback a delete job.
