ORA-32315: REFRESH FAST of "string

"."string

" unsupported after mixed DML and Direct Load

What triggered the Error:

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.

What should we do to fix it:

Use REFRESH COMPLETE. Note: you can use the DBMS_MVIEW.EXPLAIN_MVIEW() API to determine which materialized view logs omit the sequence number option.
