scenario: I have ST of product A and Product B and SL takes place on different dates. When the SL sold out from product A then product B needs to be substract.
Such as on 22.01.2021, ST Product A was 18 and items sold out until 29.01.2021 but on this dates total remaining ST Product A was 3 and Sold items were 4 so 3 - 4 = -1. So 3 items should be subtract from Product A and 1 items should be subtract from Product B. and also mark it in last 2 columns that the sold items take place from Product A or Product B.
