Locate bad references in configuration

Use the Bad References report to find bad references in configuration. Bad references are those that cannot be resolved.

Generate the Bad References report using Xoom Explorer or Xoom Processor.

The report lists all items that possess bad references. For example, in the following screenshot we can see that the item Group[Engineers - LBS]] contains one bad reference of type District.

If we look at the XoomXML for that item (generated by Settings Migration Tool), we can follow the path, given in the report, to find the bad reference: /Body/CONDITION/CONDITION/VALUE 124422148.
