物料失效验证的待定事务

最近一个项目MTL_SYSTEM_ITEMS_B表有70,000,000条记录。 用API inv_item_grp.update_item失效起来巨慢，平均2分钟一个物料。

为此看了看oracle验证的东西，想直接把他验证的事务处理处理完毕后直接更新表或者更改标准API，去掉更新验证的东西，让失效能很快的达到目的。

通过研究，在处理完待定事物处理之后，以下是2个快速失效方案：

1. 直接更新MTL_SYSTEM_ITEMS_B， 确定可行率：80% ，需更新11个字段， 效率：最快捷

2. 更改INVUPD2B.update_validations，在begin后添加代码 return 0;， 确定可行率：99%， 效率： 较为快捷

详细的研究过程就不发了，复制到CSDN超级困难。

发一下oracle对于失效检测的待定事务处理(版本R12.1.3)：
