The Ignore cache checkbox on the sys_properties table controls how ServiceNow handles cache invalidation when a system property is updated. It does not simply mean that caching is disabled.

  • Open sys_properties.list in the Application Navigator.

  • Open the required system property.

  • Review the Ignore cache checkbox.

  • If selected, only the system property cache is flushed when the property changes.

  • If cleared, the update triggers a broader server-side cache flush so dependent cached values are refreshed.

  • Save the record after confirming the expected behavior.

I would generally recommend enabling Ignore cache for properties that change frequently and whose values are stored only in the system property table. However, don't enable it blindly, as other cached values that depend on the property may remain unchanged until refreshed.

If the property is frequently updated by a Flow or scheduled job, consider storing the configuration in a dedicated table instead of repeatedly updating sys_properties.

Test any changes in a sub-production instance first, as cache flushes can affect overall instance performance.
