I am stuck with a logical problem in my application. I have been trying to find the allocated cost based on their Customers ID using SQL.
My problem goes like this: In first table(Table1) I have BusinessUnit, ProductFamily,Cost
in the other(Table2) I have BusinessUnit, CustomerID, ProductFamily , Revenue
Data as below `
BU Product_Family Cost
------------------------------
4 Fiat 145
5 TI 200
`
BU CID Product_Family Revenue
-----------------------------------
4 c1 Fiat 50
4 c2 Fiat 80
4 c3 Fiat 40
5 c3 TI 40
5 c2 TI 80
Sum_of_Revenue for BU,Product_Family wise [4,Fiat]: (50+80+40) = 170
Now I need to find the allocated cost per CID(Customer_ID) : Calculation goes like this
Allocated Cost for C1 for BU,Product_Family wise [4,Fiat] = [Table1.Cost(Here the value is 145) * Table2.Cost of C1 Customer(here the value is 50)] / Sum_of_Revenue BU,Product_Family wise [4,Fiat] (here the value is 170).
And for C3 [BU,Product_Family wise (5,TI)]the value should be (200*40)/(40+80)
Would you please suggest me how would I desing my code to accomplish this task.
