Determine if the sys_class_name on a CI was modified - Support and Troubleshooting

Determine if the sys_class_name on a CI was modified Issue  If you have duplicate or corrupted CIs in the CMDB, it may be caused by the sys_class_name on the CI being modified.

Resolution To determine if the sys_class_name on a CI was modified:

Determine what system class a CI belongs to. Go to your personalized list view and add the Class field in the list view. The Class field displays what system class (sys_class_name) the record belongs to. Ensure that you have auditing enabled on the associated table. For more information, see Enable auditing for a table in the ServiceNow product documentation. You can now look at the change history for the Class , as shown in the following image. For more information, see Viewing change history in the ServiceNow product documentation.

If the sys_class_name of a CI was wrongly changed, then you can still reset the Class on CI to the correct desired class. To do this:

Go to the specific CI in list view, and double-click on the Class field. This shows you a choice list of various system classes. Select the desired class and click Save .
