## Summary of Robust import set transformer properties

Robust import set transformer properties in ServiceNow define how updates to Configuration Items (CIs) are managed during import set processing, specifically at the Integration Result Engine (IRE) payload level.
These settings control whether updates allow downgrades, upgrades, class switching, and how CI reclassification is handled.
Properties configured here apply globally to all rows in an import unless overridden at the individual item level using IntegrationHub ETL.

This configuration is essential for customers managing CI imports to ensure data integrity and control over how CIs evolve during automated updates.

## Key Features

* **Update Control Properties:**
  * `updateWithoutDowngrade`: Allows updates without permitting downgrades (default false).
  * `updateWithoutUpgrade`: Allows updates without permitting upgrades (default false).
  * `updateWithoutSwitch`: Allows updates without permitting class switching (default false).
* **CI Class Reclassification Properties:**
  * `classDowngrade`: Permits updating the CI class to a parent class higher in the hierarchy (default false).
  * `classUpgrade`: Permits updating the CI class to a higher-level parent class (default false).
  * `classSwitch`: Permits switching the CI class to a different branch with different attributes (default false).
* **Identification Priority Property:**
  * `skipsysobjectsourcematching`: When true, prioritizes IRE identification processes over sysobjectsource lookup to uniquely identify CIs, helping prevent duplicates when source attributes change. Defaults to false.

## Practical Implications for ServiceNow Customers

By configuring these properties, customers can tightly control how imported CI data is merged or updated, preventing unintended downgrades, upgrades, or class changes that could impact CMDB accuracy. Adjusting the `skipsysobjectsourcematching` property helps manage CI identification logic to reduce duplicates caused by changing source attributes.

These settings are accessible under **System Import Sets \> Administration \> Robust Import Set Transformers** and can also be managed via system properties. Understanding and configuring these properties according to your organization's CI management policies ensures consistent and reliable CMDB data during integration and import processes.  
Properties that define the types of updates that are permitted.

## Properties for CI reclassification {#robust-import-set-xform-props__section_ccb_fxv_hrb}

To configure properties, navigate to System Import SetsAdministrationRobust Import Set Transformers.

The properties defined in the Robust Import Set Transformers form are at the IRE payload
level and apply to all rows for the given import. If you define properties at the individual
item level using IntegrationHub ETL, they take priority over properties defined at the IRE
payload level. For more details about CI reclassification, see, [CI reclassification during IRE
processing](https://www.servicenow.com/docs/access?context=c_CIReclassification&version=brazil&pubname=brazil-servicenow-platform&ft:locale=en-US).

| ire.input.items.classDowngrade | true/false | Valid values: * true: Update the CI class to a class that is higher in the class hierarchy, and the newly assigned class is a parent of the current class. * false: Update the item but don't permit a class downgrade. {#robust-import-set-xform-props__ul_vcv_4th_krb} Default: false |
| ire.input.items.classUpgrade | true/false | Valid values: * true: Update the CI class to a class that is higher in the class hierarchy, and the newly assigned class is a parent of the current class. * false: Update the item but do permit a class downgrade. {#robust-import-set-xform-props__ul_n2d_qth_krb} Default: false |
| ire.input.items.classSwitch | true/false | Valid values: * true: Update the attribute. The newly assigned class is in a different branch in the class hierarchy and has a different set of attributes than the current class. * false: Update the attributes but don't permit a class switch. {#robust-import-set-xform-props__ul_w2d_qth_krb} Default: false |
| ire.skip_sys_object_source_matching | true/false | Determines whether IRE identification processes have the priority in being used to uniquely identify CIs in a payload, over the use of sys_object_source lookup. When set to true, the system prioritizes sending any payload that contains a criterion attribute to be processed by IRE identification instead of using sys_object_source lookup. This can be useful in situation that can potentially generate duplicate CIs. For example, using sources in which identifying attributes are changing while the source native key isn't. However, when source_native_key is the only identifiable attribute (for example, if none of the identification rules can run because attributes and values for rule identifiers aren't present in the payload), then source_native_key is used for identification even when the property is set to true. * Type: true \| false * Default: false * Learn more: * Location: [Add to System Properties \[sys_properties\]](https://www.servicenow.com/docs/access?context=t_AddAPropertyUsingSysPropsList&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US) table. {#robust-import-set-xform-props__ul_nm3_gqz_v2c} |
