Re: How to calculate Surplus w.r.t the previously changed value?

Hi Nithin,

I am ordering by ID. I am not able to track the changes. My problem will be solved if I am able to track the change.

427- 300 = 127, But my requirement is to take the changed value: 713 - 300 = 413

I have used something like this:

SELECT ID,PRODUCTID,RECEIPTQTY,FIXEDPEGGEDQTY, SURPLUSSHORTAGEQTY ,

COALESCE(LAG(SURPLUSSHORTAGEQTY) over (partition by PRODUCTID order by ID), RECEIPTQTY   ) - FIXEDPEGGEDQTY as SURPLUSSHORTAGEQTY
