This enables better data quality and integrity across your CMDB. ## Procedure 1. Navigate to **All** > **CMDB Workspace** > **CMDB 360**. 2. Select **Create Query**. 3. In the query type window, select **Compare attribute values**. 4. Define the query parameters: 1. Select **CI Class** you want to analyze \(for example, cmdb\_ci\_computer\). 2. Apply filters to narrow the scope \(for example, Discovery source contains "TSOM"\). 3. Select attributes to compare values across different discovery sources. 4. Choose the sources to compare \(for example, Discovery, SCCM\). 5. Select **Compare to CMDB** to compare discovery source data to the current Baseline CMDB. 6. Select **Save**, provide a name for the query, and then select **Run** to generate the results. 5. Select **Schedule** to set up the query to run at defined intervals. ## Result The report displays a comparison of attribute values across sources: - Source 1: Current CMDB record. - Source 1 Value: Value updated by the most recent discovery source. - Source 2: Previous discovery source. - Source 2 Value: Value provided by the earlier discovery source. Each discrepancy is listed as a separate record when a CI has been updated by multiple sources. **Parent Topic:**[Using Telecommunications Service Operations Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-service-ops/telecommunications-service-operations-management/using-tsom.md) **Related topics** [Configure attribute value discrepancy in CMDB 360](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-service-ops/telecommunications-service-operations-management/configure-attribute-value-discrepancy-in-cmdb-360.md) [Control CI attribute updates using Reconciliation rules](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-service-ops/telecommunications-service-operations-management/control-ci-attribute-updates-using-reconciliation-rules.md)
