I need Cumulative sum for 'Order Qty'.
When i use this code with Select fields as "Sales_Year","Sales_Billing_Date", "Order_Qty" am getting the result i needed.
Code used:
"Sales_Year",
"Sales_Billing_Date",
"Order_Qty" ,
SUM ("Order_Qty") OVER ( ORDER BY "Sales_Billing_Date") AS "SUM_VAL"
FROM
( SELECT
"Sales_Year",
"Sales_Billing_Date" ,
SUM("Order_Qty") AS "Order_Qty" FROM "PS_WARRANTY_ANALYTICS"."PS_PAL_DLR_SALES"
GROUP BY "Sales_Year","Sales_Billing_Date"
)
But i select more fields(added "Equipment_ID") its not getting grouped by as its unique field. how can in achieve cumulative value including this field code added
"Equipment_ID"
SELECT
"Sales_Year",
"Sales_Billing_Date",
"Equipment_ID",
"Order_Qty" ,
SUM ("Order_Qty") OVER ( ORDER BY "Sales_Billing_Date") AS "SUM_VAL"
FROM
( SELECT
"Sales_Year",
"Sales_Billing_Date" ,
"Equipment_ID",
SUM("Order_Qty") AS "Order_Qty" FROM "PS_WARRANTY_ANALYTICS"."PS_PAL_DLR_SALES"
GROUP BY "Sales_Year","Sales_Billing_Date","Equipment_ID"
)
cumulated:

Assuming your sub query returns something like this

And assuming sap behaves like sqlserver then
select * ,
sum(sumqty) over (partition by year(orderdate), orderdate order by productid ) cumtot
from
(
select year(orderdate) yyyy,orderdate,productid,sum(OrderQty) sumqty
from [AdventureWorks2012].[Sales].[SalesOrderHeader] soh
join [AdventureWorks2012].[Sales].[SalesOrderDetail] sod on sod.SalesOrderID = soh.SalesOrderID
where year(orderdate) = 2005 and month(orderdate) in (7,8,9) and day(orderdate) in (1,2,3)
AND PRODUCTID < 730
group by year(orderdate),orderdate,productid
) s
order by yyyy,orderdate,productid
Produces
yyyy orderdate productid sumqty cumtot
