Question

我有这个存储过程，它提供了一些库存数据和标准格式，并没有考虑任何父子关系。这是数据的当前视图以及许多其他列：

我正在尝试在此报告中引入父/子关系。所以我修改了所有查询以引入所有父/子数据。数据需要以特定方式呈现。如下图：

基本上，需要首先列出每个父项，然后列出所有子记录。然后找到要在父行上显示的所有子项的这些记录。

the min of all child "1st Receipt Date", 
max of all child "Last Receipt Date", 
Sum of all child "On Hand"
Sum of all child "Sales Unit"
Mths Supply will be calculated from the total On Hand and Sales Units

我不知道如何以这种方式安排数据。会非常欣赏一些方向。

提前致谢。

--------------------------------------------------------------------------------------------------------
Declare @Inv table (SKU int,FirstReceiptDate Date,LastReceiptDate Date,OnHand int,SalesUnits int)
Insert Into @Inv (SKU,FirstReceiptDate,LastReceiptDate,OnHand,SalesUnits) values
(456,'2014-03-15','2014-12-14',0,15),
(789,'2014-05-30','2014-12-15',10,35),
(321,'2014-07-31','2016-03-16',112,60)

Declare @Hier table (SKU int,PtSKU int,PS int,Title varchar(50)) 
Insert into @Hier (SKU,PtSKU,PS,Title) values
(123,0,0,'SKU Tile 123'),
(456,123,10,'Some Other Title SKU 456'),
(789,123,20,'This is the Title for Title SKU 786'),
(321,123,30,'Finally Tile 321')

-- My hierarchies are pretty static so they are rebuilt as needed
-- The real power is using the range key.  You can aggregate data without

-- I should not that I added a Presentation Sequence (PS) and Title to the Hierarcy
-- The PS is used to control the presentation order.  This can be alphabetical as well
