How does Normalization Data Service guided setup update the existing core_company tableIssue In Normalization Data Service guided setup, the steps are: Activate PluginDownload Normalized Data Update Reference Qualifiers Normalization Properties Normalize Configuration Items (CMDB)Normalize Configuration Items (CMDB) Model There seems no step to normalize the existing company records in core_company table. However, the step 5 "Normalize Configuration Items (CMDB)" actually not only normalizes the CMDB but also normalizes the existing company records in core_company table. If you stop at step 4 "Normalization Properties", you would find all the company records not updated and having field Normalized = false. This means you need to at least complete step 5 even though you don't need to normalize the CMDB. (There might be future enhancement to normalize the core_company records before step 5)
