Can Updated by and Created by fields be changed from user ID to user nameSummaryCustomer would like the OOB Updated by and Created by fields to be changed to display user name instead of the OOB User IDReleaseAnyInstructionsUnfortunately, while possible, we would strongly recommend against modifying the sys_created_by/sys_updated_by fields with a username instead of a UserID. These are system fields and should not be modified. Showing the User ID on the 'Updated By' field is the Out of The Box behavior of the ServiceNow Platform. The platform populates these fields with UserID(sys_user.user_name) value because the userID field is unique. The user name is not unique, which is why having the user name copied instead of userID is not a good idea. As multiple user records can have the same name. In addition, changing the field also risks impacting ACL's and other internal processes that use the UserID. All sys_created_by and sys_updated_by fields are String type, not a reference to the incident table, and don't contain a sys_id. It's a simple string, most likely for performance reasons. If you modify its behavior, you may suffer from unexpected side-effects later on. Should you still want to have a field that contains the username, then you would need to create a custom field and an associated business rule that populates it. Leave the OOB fields for the system, and create a new one for your own usage and requirement. Then, you will have to configure a business rule to run on insert & updates to set the new field.
