"REFRESH FAST of \"%s\".\"%s\" unsupported after mixed DML and Direct Load"
*Cause: One or more of the materialized view logs on the detail tables
referenced by the specified materialized view omits the sequence
number option. Such a log cannot be used to refresh a
materialized view after deletes or updates and direct path insert.
*Action: Use REFRESH COMPLETE. Note: you can use the
DBMS_MVIEW.EXPLAIN_MVIEW() API to determine which materialized view
logs omit the sequence number option.
