distcode YTD (YTD Desc order)
D101 4000
D102 2000
D103 500
90% sales
ie., sum(YTD)*90% : 6500*90%=5850
I want to find out for 5850, count(distcode) contribution (ie.d how many distributor summing YTD comes to 5850 from YTD desc order ,we have to consider)
If i add 2 disttributor YTD then it comes near to 5850
result is count(Distcode)=2
is it possible write sql statement

DECLARE @tab TABLE(distcode VARCHAR(5), YTD INT)
INSERT INTO @tab VALUES('D101', 4000 ), ('D102', 2000), ('D103', 500)
SELECT COUNT(distcode)+1 DistCount
FROM (SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.distcode <= a.distcode) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM @tab a
)t
WHERE RunningTotal <= Sales

will not work always
see this sample data
distcode YTD (YTD Desc order)
D101 4000
D102 1850
D103 300
D104 350

not again correct as its not considering the order of distcode
DECLARE @tab TABLE(distcode VARCHAR(5), YTD INT)
INSERT INTO @tab
--VALUES('D101', 4000 ), ('D102', 2000), ('D103', 500)
SELECT 'D103', 4000 UNION ALL
SELECT 'D102', 1000 UNION ALL
SELECT 'D101', 900 UNION ALL
SELECT 'D106', 550 UNION ALL
SELECT 'D107', 200 UNION ALL
SELECT 'D105', 250 UNION ALL
SELECT 'D104',150
--Bandi solution
SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.YTD >= a.YTD) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM @tab a
;With CTE
AS
(
SELECT a.distcode, a.YTD, (SELECT SUM(b.YTD) FROM @tab b WHERE b.YTD >= a.YTD) RunningTotal, 0.9*SUM(YTD) OVER() Sales
FROM @tab a
)
SELECT COUNT(distcode)+1 DistCount
FROM CTE t
WHERE RunningTotal < Sales
--Visakh Solution
;With CTE
AS
(
SELECT a.distcode, a.YTD, 0.9*SUM(YTD) OVER() AS [90PC],
ROW_NUMBER() OVER (ORDER BY distcode) AS RN
FROM @tab a
)
SELECT RN AS DistCount
FROM CTE c1
OUTER APPLY (SELECT SUM(YTD) AS RunningTotal FROM CTE WHERE RN < c1.RN) c2
WHERE COALESCE(RunningTotal,0)<= [90PC]
AND COALESCE(RunningTotal,0) + YTD > [90PC]
output
-----------------------------------------
distcode YTD RunningTotal Sales
D103 4000 4000 6345.0
D102 1000 5000 6345.0
D101 900 5900 6345.0
D106 550 6450 6345.0
D107 200 6900 6345.0
D105 250 6700 6345.0
D104 150 7050 6345.0
