sql2008中的运行计数器

我正在尝试为SQL 2008中正在运行的库存需求报告建立一个临时表。我可以得到我正在寻找的结果，直到我找到一个有多行的发票。以下是迄今为止的代码：

--Gather Current Order Data
DECLARE @b TABLE ([Planned Shipment Date] DATE, [Order] VARCHAR(15), [Line Number] VARCHAR(15), [Location] VARCHAR(15), [Item] VARCHAR(15), [QuantityUsed] INT)

INSERT INTO @b
SELECT [Planned Shipment Date], [Document No_], [Line No_], [Location Code], No_, CAST(SUM([Outstanding Quantity]) AS INT)
FROM [STAGE].[dbo].[TRU$Sales Line]
WHERE [Document No_] LIKE 'SO%'
AND [Gen_ Prod_ Posting Group] IN ('TOY', 'AUDIO', 'BICYCLE')
AND [Outstanding Quantity] <> 0
GROUP BY [Document No_], [Location Code], [Line No_], [Planned Shipment Date], No_
ORDER BY [Planned Shipment Date], [Document No_], [Line No_], [Location Code], No_

--Gather Current Inventory Data
DECLARE @a TABLE ([Item] VARCHAR(15), [Location] VARCHAR(15), [Inventory] INT)

INSERT INTO @a
SELECT [Item No_], [Location Code], CAST(SUM([Quantity]) AS INT)
FROM [STAGE].[dbo].[TRU$Item Ledger Entry]
GROUP BY [Item No_], [Location Code]
ORDER BY [Item No_], [Location Code]

DROP TABLE ##TEMP
--Insert to a temp table for testing
SELECT [Planned Shipment Date], [Location], [Item], [Order], [Line Number], 
[Outstanding Qty], [Total Inventory], [Running Order Total]
INTO ##TEMP
FROM
 (SELECT 
   [order].[Planned Shipment Date]
  ,[order].[Location] 
  ,[order].[Item] 
  ,[order].[Order]
  ,[order].[Line Number]
  ,0 AS [Outstanding Qty]
  ,(SELECT SUM(inventory)
    FROM @a inv
    WHERE inv.item = [order].[Item] 
    AND inv.location = [order].[Location]) AS [Total Inventory] 
  ,(SELECT SUM(QuantityUsed) 
    FROM @b prevorder 
    WHERE prevorder.item = [order].[Item] 
    AND prevorder.location = [order].[Location] 
    AND prevorder.[order] <= [order].[Order]
    ) AS [Running Order Total]
  FROM @b [order] 
 ) AS OrderExtended 
--WHERE [Total Inventory] < [Running Order Total]
ORDER BY [Planned Shipment Date], [Order], [Line Number], [Location], [Item] ASC
GO
--Display outstanding quantity to ship on the temp table
UPDATE ##TEMP
SET [Outstanding Qty] = SL.[Outstanding Quantity]
FROM ##TEMP T, [TRU$Sales Line] SL
WHERE T.[Order] = SL.[Document No_]
AND T.[Line Number] = SL.[Line No_]
GO

我得到如下结果（未完成数量的不正确运行总数）：

我所期望的是（未完成数量的真实运行总数）：

似乎当订单上包含不同的发货日期（每个订单不止一行）时，我的查询就被打乱了。我错过了什么？我看了这么多，恐怕看不出明显的解决办法

谢谢你的帮助，

您必须在上一个订单时限制[行号]。订单=[订单]。订单：

(SELECT SUM(QuantityUsed) FROM @b prevorder        
 WHERE prevorder.item = [order].[Item] AND prevorder.location = [order].Location]        
 AND (prevorder.[order] < [order].[Order] OR (prevorder.[order] = [order].[Order]         
 AND prevorder.[Line Number] <= [order].[Line Number]))         
 AS [Running Order Total]

（从@b prevorder中选择SUM（QuantityUsed）
其中prevorder.item=[order].[item]和prevorder.location=[order].location]
和（prevorder.[order]<[order].[order]或（prevorder.[order]=[order].[order]
和订单。[行号]
