Control CI attribute updates using Reconciliation rules
To prevent specific attributes of a Configuration Item (CI) from being overwritten by Discovery or other data sources, use Reconciliation Rules. These rules define which data source is trusted to update a particular attribute when multiple sources provide values.

Por Que e Quando Desempenhar Esta Tarefa
Reconciliation Rules are processed by the Identification and Reconciliation Engine (IRE) and are essential for maintaining data integrity in the CMDB.
Use Case: If you want to prevent Discovery from updating a set of attributes while allowing another source (like SCCM or manual entry) to update them, define a rule that excludes the Discovery source.
Nota:
Only one
Reconciliation Rule should be active for a specific CI class and attribute combination to avoid conflicts.
Procedimento
- Navigate to .
- Select the target CI class (e.g., cmdb_ci_computer).
- In the Reconciliation Rules tab, click New to create a rule.
- Provide the rule name and select the Discovery source to apply the rule to.
- Specify the attributes that this rule will govern.
- Set the source precedence to allow only the selected sources to update the specified attributes.
Resultado
Certain CI attributes will no longer be updated by untrusted or lower-priority data sources like Discovery. Only the sources defined in the rule (e.g., SCCM, manual updates) will be allowed to update those attributes.
