使用收据交易按位置进行账龄分布

问题描述 投票：0回答：1

我有一个库存查询，可以按位置提供特定商品的可用库存：

Stock_By_Location_By_Item

另一个查询按数量、日期和收据 txn 以及同一商品的编号按降序排列提供所有收据：

Receipt_History_By_Item_By_Date_By_Quantity

我们想要使用 SQL 查询得到如下所示的输出：

Desired_Output

我想添加每个地点可用库存的收据详细信息（交易代码、编号、数量和日期），并根据比较可用库存的收据数量进行分配。收货详细信息和数量循环，直到总数与库存数量匹配，然后获取下一个收货并循环，直到所有位置数量与收货匹配。

我需要您的专业知识来解决这个问题。谢谢。
