Total function in script

[venkatbza]

Hello friends,

How to convert front end chart expression in back end script for below mentioned expression.

=Sales/Sum(TOTAL{1} Sales)

I have a material and sales fields now i have to create a field called  'percentage of total sales '. In the front end chat above expression is working fine, but i want this expression move to back end script. 

		OUTPUT column
Material	Sales	sales/sum(sales)
1	10	10/129 =0.77519
2	13
3	20
4	5
5	15
6	66
Total	129

Thanks,

Venkat

Try this

Table:
LOAD * INLINE [
    Material, Sales
    1, 10
    2, 13
    3, 20
    4, 5
    5, 15
    6, 66
];

Left Join (Table)
LOAD Sum(Sales) as TotalSales
Resident Table;

FinalTable:
LOAD *,
	 Sales/TotalSales as [percentage of total sales]
Resident Table;

DROP Table Table;
