查找物料的时候报错 没有输入值

解决方法：

针对FORM做trace

多查看几个生成的trace

搜索 MTL_SYSTEM_ITEMS_b 的信息

查看到最后面的语句（一般可直接查看）

看sql 哪地方不满足

这边是这块：

SELECT MTL_SYSTEM_ITEMS_VL.SEGMENT1 C0,MTL_SYSTEM_ITEMS_VL.DESCRIPTION

  "说明"

FROM

 MTL_SYSTEM_ITEMS_VL WHERE 1=1 AND MTL_SYSTEM_ITEMS_VL.ENABLED_FLAG = ‘Y‘ AND

  TO_DATE(:A00,‘YYYY/MM/DD HH24:MI:SS‘) BETWEEN

  NVL(TRUNC(MTL_SYSTEM_ITEMS_VL.START_DATE_ACTIVE),TO_DATE(:A01,‘YYYY/MM/DD

  HH24:MI:SS‘)) AND NVL(TRUNC(MTL_SYSTEM_ITEMS_VL.END_DATE_ACTIVE),

  TO_DATE(:A02,‘YYYY/MM/DD HH24:MI:SS‘)) AND (MTL_SYSTEM_ITEMS_VL.SEGMENT1

  LIKE :A03 OR MTL_SYSTEM_ITEMS_VL.SEGMENT1 IS NULL ) AND

  MTL_SYSTEM_ITEMS_VL.ORGANIZATION_ID = :A04 AND  ( ((:A05 = 1 AND

  ENG_ITEM_FLAG = ‘N‘) OR         (:A06 = 2))        AND

  INVENTORY_ITEM_STATUS_CODE NOT IN (:A07,:A08)                            

  AND INVENTORY_ITEM_STATUS_CODE <> (SELECT NVL(BOM_DELETE_STATUS_CODE,‘A‘)

  FROM BOM_PARAMETERS WHERE ORGANIZATION_ID = :A09)        AND

  NVL(APPROVAL_STATUS,‘A‘) = ‘A‘ AND         ((BOM_ITEM_TYPE = 4 AND :A0A =

  1) OR         (BOM_ITEM_TYPE = 3 AND :A0B = 1) OR         (BOM_ITEM_TYPE =

  2 AND :A0C = 1) OR         (BOM_ITEM_TYPE = 1 AND :A0D = 1))        AND    

     ((:A0E = ‘N‘ AND EFFECTIVITY_CONTROL = 1) OR         (:A0F = ‘Y‘)) )   

  ORDER BY MTL_SYSTEM_ITEMS_VL.SEGMENT1;

定位到

select BOM_DELETE_STATUS_CODE from BOM_PARAMETERS

应为inactive。而环境是active

定位到界面是
