Calculate NPI (non-productive Inventories in DAX

Hi v-huizhn-msft,

I have found a solution as below in Sql. How to calculate in dax?

CREATE TABLE dbo.YourTable
([Date_] date, [Product] nvarchar(50), [Amount] DECIMAL(10,3), [Stock] DECIMAL(10,3))
;

INSERT INTO dbo.YourTable
([Date_], [Product], [Amount], [Stock])
VALUES
('2018-01-01', 'Urun1', 10,46 ),
('2018-01-02', 'Urun1', 20,46 ),
('2018-01-03', 'Urun1', 30,46 ),
('2018-01-04', 'Urun1', 1, 46 ),
('2018-01-05', 'Urun1', 3, 46 ),
('2018-01-06', 'Urun1', 5, 46 ),
('2018-01-01', 'Urun2', 2, 6),
('2018-01-02', 'Urun2', 4, 6)
;

SELECT *,
case when MIN(Stock) OVER(PARTITION BY Product ) > SUM(Amount) OVER(PARTITION BY Product ORDER BY Date_ desc)
Then Amount
when min(Stock) OVER(PARTITION BY Product)-(SUM(Amount) OVER(PARTITION BY Product ORDER BY Date_ desc)-Amount) <0 Then 0
Else min(Stock) OVER(PARTITION BY Product)-(SUM(Amount) OVER(PARTITION BY Product ORDER BY Date_ desc)-Amount) End RemainingStock
FROM dbo.YourTable
ORDER BY Product,Date_ ;

drop table YourTable
