Hi @lmu 

Good day!!

Error:

Exception:ErrorClass=INVALID_PARAMETER_VALUE.PATH_BASED_ACCESS_NOT_SUPPORTED_FOR_TABLES_WITH_ROW_COLUMN_ACCESS_POLICIES] Path-based access to table catalog_x.schema_y.rls_dbx_test with row filter or column mask not supported.

Root Cause Analysis:

I would like to inform you that path-based access to files in tables with policies(Row Filter/Column Masking) is not supported.

(https://docs.databricks.com/en/tables/row-and-column-filters.html#limitations:~:text=Path%2Dbased%20...)

Solution:

As they are accessing the table using the path, the correct way will be to only use the table name if they want to continue using the new table policies.
