报表库逻辑备有一个错误：
ORA-31693: Table data object "BI_ETL"."xxx" failed to load/unload and is being skipped due to error:
ORA-02354: error in exporting/importing data
ORA-39826: Direct path load of view or synonym (BI_ETL.xxx) could not be resolved.
?
百度了一下，是因为这个对象在导出过程中被删掉了导致的bug，
去报表库验证了一下对象xxx确实不存在
然后在本地环境测试了一下，没有能重现错误ORA-39826: Direct path load of view or synonym (BI_ETL.WY_CAR_ZJ_UW) could not be resolved.
下面是试验过程：
1、创建张测试表
SQL> create table scott.change_tbs as select * from dba_objects;
Table created.
3、执行导出脚本，开始后删除测试表
