Logic to find Quantity

Hi All,

Thanks in Advance 

I am stuck with this scenario, could you plz help me how to write script in backend to find Quantiy, show in below table. Here i want to show such data in Bar chart, weekNumber As Dimension and SIN,SOUT,Quantity as Measure.I want to write expression for Quantiy in the backend only.

  Week1 Week2 Week3 Week4
Sell in 1000 0 0 0
Sell Out 700 420 80 45
Returns 0 20 0 10
Quantity 300 300+(0-420)+20=100 100+(0-80)+0=-20 20+(0-45)+10=-15

 

For understanding purpose only i show like cross table, actually my data is like normal table with col weekNO, SIN,SOUT, Return. I want expression for Quantity in backend only. I used Previous() function but i am not able to write complete logic.
