edit：当用户Larna请求为子查询表创建/插入时，我也添加了这些。
以下查询返回：
DocNum ItemCode Planned Qty WhsCode BinCode QuantityToPick
901903 A00001 12.000000 98 98-A001 7.000000
901903 A00001 12.000000 98 98-A002 5.000000 --sum of 5 and 7 makes 12
901904 A00001 17.000000 98 98-A001 7.000000
901904 A00001 17.000000 98 98-A002 6.000000
901904 A00001 17.000000 98 98-A003 4.000000 --sum of 7,6 and 4 makes 17
But I want to have this result:
DocNum ItemCode Planned Qty WhsCode BinCode QuantityToPick
901903 A00001 12.000000 98 98-A001 7.000000
901903 A00001 12.000000 98 98-A002 5.000000 --sum of 5 and 7 makes 12
-- continue from bin code 98A002 for the new docnum as we had 5 out of 6 where consumed
901904 A00001 17.000000 98 98-A002 1.000000
901904 A00001 17.000000 98 98-A003 12.000000
901904 A00001 17.000000 98 98-A004 4.000000 --sum of 1,12 and 4 makes 17

这实际上比第一次听起来容易。但是，您将首先需要处理一些问题-您还需要针对所需数量进行总计：
SELECT OWOR.docNum, WOR1.itemCode, plannedQty,
SUM(plannedQty - issuedQty) OVER (PARTITION BY WOR1.itemCode
ORDER BY OWOR.docEntry) - (plannedQty - issuedQty) AS prevTotalNeeded,
SUM(plannedQty - issuedQty) OVER (PARTITION BY WOR1.itemCode
ORDER BY OWOR.docEntry) AS runningTotalNeeded
FROM OWOR
JOIN WOR1
ON WOR1.docEntry = OWOR.docEntry
WHERE OWOR.status = 'R'
....结合“需要运行的前一列”（并假设以前的总数量），我们现在正在查看overlapping range query。
与您的BINSTOCK（稍作修改）结合在一起：
SELECT *
FROM (SELECT itemCode, whsCode, binCode, quantity,
SUM(quantity) OVER (PARTITION BY itemCode ORDER BY binCode) - quantity AS prevTotalQuantity,
SUM(quantity) OVER (PARTITION BY itemCode ORDER BY binCode) AS runningTotalQuantity
FROM (SELECT OIBQ.itemCode, OIBQ.whsCode, OBIN.binCode, SUM(OIBQ.onHandQty) AS quantity
FROM OIBQ
JOIN OBIN
ON OBIN.absEntry = OIBQ.binAbs
GROUP BY OIBQ.itemCode, OIBQ.whsCode, OBIN.binCode) TotalQuantity
) BINSTOCK
JOIN (SELECT OWOR.docNum, WOR1.itemCode, plannedQty,
SUM(plannedQty - issuedQty) OVER (PARTITION BY WOR1.itemCode ORDER BY OWOR.docEntry) - (plannedQty - issuedQty) AS prevTotalNeeded,
SUM(plannedQty - issuedQty) OVER (PARTITION BY WOR1.itemCode ORDER BY OWOR.docEntry) AS runningTotalNeeded
FROM OWOR
JOIN WOR1
ON WOR1.docEntry = OWOR.docEntry
WHERE OWOR.status = 'R') WOPICK
ON WOPICK.itemCode = BINSTOCK.itemCode
AND WOPICK.prevTotalNeeded <= BINSTOCK.runningTotalQuantity
AND WOPICK.runningTotalNeeded >= BINSTOCK.prevTotalQuantity
...将产生下表：
itemCode | whsCode | binCode | quantity | prevTotalQuantity | runningTotalQuantity | docNum | itemCode | plannedQty | prevTotalNeeded | runningTotalNeeded :------- | :------ | :------ | :-------- | :---------------- | :------------------- | -----: | :------- | :--------- | :-------------- | :----------------- A00001 | 98 | 98-A001 | 7.000000 | 0.000000 | 7.000000 | 901903 | A00001 | 12.000000 | 0.000000 | 12.000000 A00001 | 98 | 98-A002 | 6.000000 | 7.000000 | 13.000000 | 901903 | A00001 | 12.000000 | 0.000000 | 12.000000 A00001 | 98 | 98-A002 | 6.000000 | 7.000000 | 13.000000 | 901904 | A00001 | 17.000000 | 12.000000 | 29.000000 A00001 | 98 | 98-A003 | 12.000000 | 13.000000 | 25.000000 | 901904 | A00001 | 17.000000 | 12.000000 | 29.000000 A00001 | 98 | 98-A006 | 15.000000 | 25.000000 | 40.000000 | 901904 | A00001 | 17.000000 | 12.000000 | 29.000000
...。然后，通过明智的CASE语句，我们可以将重叠的三个四个（不是三个）条件转换为最终的总计：
SELECT WOPICK.docNum, WOPICK.itemCode, WOPICK.plannedQty,
BINSTOCK.whsCode, BINSTOCK.binCode,
CASE WHEN WOPICK.prevTotalNeeded < BINSTOCK.prevTotalQuantity
AND WOPICK.runningTotalNeeded > BINSTOCK.runningTotalQuantity
THEN BINSTOCK.quantity
WHEN WOPICK.prevTotalNeeded >= BINSTOCK.prevTotalQuantity
AND WOPICK.runningTotalNeeded <= BINSTOCK.runningTotalQuantity
THEN WOPICK.neededQuantity
WHEN WOPICK.runningTotalNeeded <= BINSTOCK.runningTotalQuantity
THEN WOPICK.runningTotalNeeded - BINSTOCK.prevTotalQuantity
WHEN WOPICK.prevTotalNeeded >= BINSTOCK.prevTotalQuantity
THEN BINSTOCK.runningTotalQuantity - WOPICK.prevTotalNeeded
END AS quantityToPick
FROM (SELECT itemCode, whsCode, binCode, quantity,
SUM(quantity) OVER (PARTITION BY itemCode
ORDER BY binCode) - quantity AS prevTotalQuantity,
SUM(quantity) OVER (PARTITION BY itemCode
ORDER BY binCode) AS runningTotalQuantity
FROM (SELECT OIBQ.itemCode, OIBQ.whsCode, OBIN.binCode, SUM(OIBQ.onHandQty) AS quantity
FROM OIBQ
JOIN OBIN
ON OBIN.absEntry = OIBQ.binAbs
GROUP BY OIBQ.itemCode, OIBQ.whsCode, OBIN.binCode) TotalQuantity
) BINSTOCK
JOIN (SELECT OWOR.docNum, WOR1.itemCode, plannedQty, plannedQty - issuedQty AS neededQuantity,
SUM(plannedQty - issuedQty) OVER (PARTITION BY WOR1.itemCode
ORDER BY OWOR.docEntry) - (plannedQty - issuedQty) AS prevTotalNeeded,
SUM(plannedQty - issuedQty) OVER (PARTITION BY WOR1.itemCode
ORDER BY OWOR.docEntry) AS runningTotalNeeded
FROM OWOR

ON WOR1.docEntry = OWOR.docEntry
WHERE OWOR.status = 'R') WOPICK
ON WOPICK.itemCode = BINSTOCK.itemCode

AND WOPICK.runningTotalNeeded >= BINSTOCK.prevTotalQuantity

注意：我几乎没有对此进行测试。我将它留给有兴趣纠正任何错误的人，但是我认为该原则是正确的。使用递归CTE来标识下一个Bin / Order，并在列中维护一堆变量以跟踪您的工作！
