# Attribute value discrepancy report

# Generate reports for attribute value discrepancies {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Use CMDB 360 to generate reports that highlight discrepancies in attribute values between different discovery sources or between a discovery source and the CMDB baseline.

## Before you begin

Role required: admin

## About this task

Attribute value discrepancy reports help identify conflicting data from multiple sources updating the same configuration item (CI). This enables better data quality and integrity across your CMDB.

## Procedure

1. Navigate to AllCMDB WorkspaceCMDB 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. **Optional:** 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.
   {#use-attribute-value-discrepancy-in-cmdb-360__substeps_ky3_dpn_zfc}
5. **Optional:** 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.
