I have two tables in direct query list of products and stock.
Relation Stock->Product
I need to calculate list of products that I don´t have in stock.
Problem is that I have written only products that have positive numbers in stock.
Product I don´t have in stock, It can´t be found in my table. For example
Product database:
Product A id
Product b id2
Product c id3
Stock list
Product B id2 6
Product C id3 1
I don´t have Product A id 0 written in stock.
