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：
/* Bug:2948014 Already supported by INVIDIT2.Insert_Cost_Details

end if;
Bug:2948014 Ended*/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。
