Hi,
When segments in Dynamics 365 Customer Insights – Journeys change from "Ready to use" to "Finished with warnings," it typically indicates that something in the segment definition or data source has caused a partial failure during evaluation. Unfortunately, the platform doesn't always provide detailed error messages directly in the UI.
Here are a few steps you can take to investigate:
Check Segment Conditions: Review the filters and conditions used in the segment. Complex logic or references to fields that have changed or been removed can trigger warnings.
Review Data Sources: If the segment relies on external data (e.g., Dataverse tables or custom entities), ensure those sources are still accessible and correctly mapped.
Audit Logs: Use the Power Platform Admin Center to check audit logs or system diagnostics. These may contain backend errors or warnings that aren't visible in the segment UI.
Segment Preview: Try previewing the segment manually. If it fails to load or shows unexpected results, that can help pinpoint the issue.
Microsoft Support: If the issue persists and no clear cause is found, consider raising a support ticket. They can access deeper logs and provide more specific guidance.
Please verify if this helps clarify the issue.
Thanks and best regards,
Daniele
