怎么查询MTL_ONHAND_QUANTITIES_DETAIL与mtl_material_transactions中的库存量持平？

网上的一篇文章：

Oracle Applications 提供了计算库存的表 MTL_ONHAND_QUANTITIES_DETAIL，开发人员只要按要求对表进行分组求和即可得到库存的现有量，这个数量就是我们在系统中查询的数量。但是如果用户要开发人员提供上个月或上个季度的库存就麻烦了。因为表MTL_ONHAND_QUANTITIES_DETAIL不提供追溯库存计算的方法。那怎么解决这个问题？

我们先来看看表MTL_ONHAND_QUANTITIES_DETAIL和 mtl_material_transactions 表的关系。mtl_material_transactions 是 Oracle Applications 库存的基表，凡是和库存有关的数据都必须存入这个表，如初期的库存导入，采购的接受入库。销售，制造的完工入库。子库转移等。mtl_material_transactions 的分组求和应该等于MTL_ONHAND_QUANTITIES_DETAIL表的分组求和，但表mtl_material_transactions
的记录一般数据庞大，不会在这个表中求现有量。mtl_material_transactions表中每笔的数据异动都会影响到MTL_ONHAND_QUANTITIES_DETAIL 的最终结果。我们通过研究发现。mtl_material_transactions 每笔入库的记录都会相应的在MTL_ONHAND_QUANTITIES_DETAI 表中增加此记录。在库存未消失前我们可以通过 mtl_material_transactions表的TRANSACTION_ID字段和表MTL_ONHAND_QUANTITIES_DETAIL的字段CREATE_TRANSACTION_ID
建立一一对应关系。

现在的问题是我在系统里通过MTL_ONHAND_QUANTITIES_DETAIL中的CREATE_TRANSACTION_ID字段 关联mtl_material_transactions只能关联到一小部分，有很多都是空的，mtl_material_transactions就没有CREATE_TRANSACTION_ID 的记录，求解

这个是按年份计算历史库存状态的查询，可以按自己要求改写出你要的语句。

select organization_id,

to_char(lastdate, 'yyyy'),

count(*) cnt,

sum(amount) value

from (

select tran.organization_id,

tran.inventory_item_id,

cict.item_number,

cict.description,

cict.primary_uom_code,

round(item_cost, 2) item_cost,

onhand,

round(onhand * item_cost, 2) amount,

lastdate,

planning_make_buy_code

from (select sum(primary_transaction_quantity) onhand,

inventory_item_id,

organization_id

from mtl_onhand_quantities_detail

where organization_id = 1

group by inventory_item_id, organization_id) moq,

(select max(transaction_date) lastDate,

inventory_item_id,

organization_id

from inv.mtl_material_transactions

where transaction_type_id not in (10008, 2, 90, 24)

and organization_id = 1

group by inventory_item_id, organization_id) tran,

(select inventory_item_id,

item_number,

description,

primary_uom_code,

planning_make_buy_code,

max(item_cost) item_cost

from CST_ITEM_COST_TYPE_V

where (organization_id in (1, 2, 3)

and cost_type_id = 1 or organization_id =4

and cost_type_id = 2)

and item_cost > 0

group by inventory_item_id,

item_number,

description,

primary_uom_code,

planning_make_buy_code) cict

where tran.inventory_item_id = moq.inventory_item_id

and tran.organization_id = moq.organization_id

and cict.inventory_item_id(+) = moq.inventory_item_id

and lastdate < to_date('2011-01-01', 'yyyy-mm-dd')

order by lastdate, item_number

)

group by organization_id, to_char(lastdate, 'yyyy')

order by organization_id, to_char(lastdate, 'yyyy')

查历史库存不能使用MTL_ONHAND_QUANTITIES之类的表，只能做核对工作，语句核心是transaction_type_id not in (10008, 2, 90, 24)，要排除这几种事务类型。留下的都是影响库存数量的事务。

注意的是当历史上事务处理出现异常时，最后计算出来的现有量会与MTL_ONHAND_QUANTITIES表中不一致，可以用当前现有量核对不一致的物料。使用这个语句

select * from (select sum(primary_quantity) qty,

inventory_item_id,

organization_id

from inv.mtl_material_transactions

where transaction_type_id not in(10008,2,90,24)

and organization_id = 2

group by inventory_item_id, organization_id) tran,

(select organization_id,

inventory_item_id,

sum(on_hand) quantity

from MTL_ONHAND_TOTAL_V where organization_id = 2

group by organization_id, inventory_item_id) Mot

where tran.inventory_item_id=mot.inventory_item_id

and tran.organization_id=mot.organization_id

and tran.qty<>mot.quantity

。查询可能会慢些，但是能接受。
