寻找EBS 11i Mtl_Item_Categories

背景：

这两天在做客户化物料编码导入的功能，发现请求运行完毕后，竟然警告了！“Warning : Validation Errors Occured. Please check MTL_INTERFACE_ERRORS Table”，不明所以，追查接口表，报错内容如下：“无法在“组织物料”中创建/删除物料控制的类别集。”,对应英文代码：“INV_CAT_CANNOT_CREATE_DELETE”。

查找问题：

比对此版本代码与过往版本代码的区别。最后发现如下：

新版本代码中采用了insert Mtl_Item_Categories_Interface 的方式以定义料以及其类别的关系；

旧版本代码中采用的是update Mtl_Item_Categories 表的方式。

为什么旧版本运行正常无警告？肯定是标准功能已经做过了insert Mtl_Item_Categories 的操作。那么该操作在什么地方实现的？

首先想到的是物料表 mtl_system_item_b 触发器。追查了半天，在trigger MTL_SYSTEM_ITEMS_T1 中发现一段代码，用于插入至Mtl_Item_Categories，不过该段代码被注释，详情如下：

原来如此，oracle修复bug时将此功能移动到其他地方了。遂前往INVIDIT2.Insert_Cost_Details 查看。在Insert_Costing_Category 过程中发现了insert，代码如下：

PROCEDURE Insert_Costing_Category
(
   X_item_id        number
,  X_org_id     number
)
IS
   l_user_id     NUMBER  :=  NVL(FND_GLOBAL.User_Id, 0);
BEGIN
   insert into mtl_item_categories
        (inventory_item_id,
         category_set_id,
         category_id,
         last_update_date,
         last_updated_by,
         creation_date,
         created_by,
         last_update_login,
         program_application_id,
         program_id,
         program_update_date,
         request_id,
         organization_id)
   select
        X_item_id,
        s.category_set_id,
        s.default_category_id,
        sysdate,
        l_user_id,
        sysdate,
        l_user_id,
        -1,
        -1,
        -1,
        NULL,
        -1,
        X_org_id
    from    mtl_category_sets_B s
    where   s.category_set_id in
        (select d.category_set_id
        from    mtl_default_category_sets d
        where   d.functional_area_id = 5)
    and not exists
       ( select  ‘x‘
         from    mtl_item_categories c
         where   c.inventory_item_id = X_item_id
         and     c.organization_id = X_org_id
         and     c.category_set_id = s.category_set_id
       );
END Insert_Costing_Category;

哈， 至此，原因找到！

方案：

将新版本中的insert interface代码修改为源版本中的update即可。
