Hi, It's difficult for me to troubleshoot without seeing the actual data. Have you validated that the raw data hasn't changed? There could be some update at your end to the format of session.user and it not matching your table. Is there any error message? If I understand correctly what you're trying to do, then a better way maybe using ABAC and adding users to groups rather than the tabular approach.https://docs.databricks.com/aws/en/data-governance/unity-catalog/abac/
