Hi @Anshul_DBX good day!

The issue you are encountering is due to a limitation in Delta Sharing. As per the provided information, Delta Sharing does not support row-level security or column masks. This means that you cannot apply row and column level filtering or data masking when using Delta Sharing to Power BI. This limitation is stated in the Databricks documentation: "Delta Sharing does not work with row-level security or column masks." Therefore, the error you are seeing is expected behaviour and not an issue with your implementation.

Best regards,
