FIFO Stock Valuation Through CTE-Recursion

524 views Asked by At

I have copied it from this site because it's been already closed but I needed it for further solution. thus, kindly help me out.....

Problem : it's calculating the closing stock valuation through FIFO of issue as a whole. but i need cost of issues into Price column in the same row it belongs to itself.

declare @Stock table (Item char(3) not null,[Date] datetime not null,TxnType varchar(3) not null,Qty int not null,Price decimal(10,2) null)
insert into @Stock(Item ,  [Date] ,        TxnType, Qty,  Price) values
('ABC','20120401','IN',    200, 750.00),
('ABC','20120405','OUT',   100 ,null  ),
('ABC','20120410','IN',     50, 700.00),
('ABC','20120416','IN',     75, 800.00),
('ABC','20120425','OUT',   175, null  ),
('XYZ','20120402','IN',    150, 350.00),
('XYZ','20120408','OUT',   120 ,null  ),
('XYZ','20120412','OUT',    10 ,null  ),
('XYZ','20120424','IN',     90, 340.00);

;WITH OrderedIn as (
    select *,ROW_NUMBER() OVER (PARTITION BY Item ORDER BY [DATE]) as rn
    from @Stock
    where TxnType = 'IN'
), RunningTotals as (
    select Item,Qty,Price,Qty as Total,0 as PrevTotal,rn from OrderedIn where rn = 1
    union all
    select rt.Item,oi.Qty,oi.Price,rt.Total + oi.Qty,rt.Total,oi.rn
    from
        RunningTotals rt
            inner join
        OrderedIn oi
            on
                rt.Item = oi.Item and
                rt.rn = oi.rn - 1
), TotalOut as (
    select Item,SUM(Qty) as Qty from @Stock where TxnType='OUT' group by Item
)
select
    rt.Item,SUM(CASE WHEN PrevTotal > out.Qty THEN rt.Qty ELSE rt.Total - out.Qty END * Price)
from
    RunningTotals rt
        inner join
    TotalOut out
        on
            rt.Item = out.Item
where
    rt.Total > out.Qty
group by rt.Item

The result is only Closing Stock as per FIFO Basis as below: Item ClsStock ABC 40000.00 XYZ 37600.00

But I need the followings Result from the same query:

Item Date TxnType OpnQty OpnRate OpnVal InnQty InnRate InnVal OutQty OutRate OutVal ClsQty ClsRate ClsVal
