# Robust import set transformer properties

Properties that define the types of updates that are permitted.

## Properties for CI reclassification

To configure properties, navigate to **System Import Sets** > **Administration** > **Robust 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/c_CIReclassification.md).

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
