Hello , i have a simple problem but i cant find a simple answer :
I tried to look on older posts but i couldnt find a solution to mi problem :
I have a model where i have :
Sales in : the sales from mi compañy to resellers
Sales Out: the sales from the resellers to end users
Initial stock : the stock on hand reported by the resellers at 01/01/2020
I need to calculate the stock by adding the sell in and sustracting the sell out :
Example :
initial stock productA in reseller A =10000 to that value i have to add the sell in and sustract the sell out
01/01/2020 stock=10000
sales in jan/2020=5000
Sales out in jan/2020=7000
stock in feb/2020= 10000+5000-7000=8000<then , this should be the initial stock in february so :
sales in feb/2020=2000
sales out feb/2020=5000
stock in march/2020=8000+2000-5000=5000 , and so on
i have a sales in table with dates and sku and reseller number , also i have a sales out table with the same dimentions , calendar table , and product table
TY!!!
