I upload a product per csv with its cost of 1000, but when I want to add that product for a purchase per csv with the same cost, it leaves it to zero in the list of products, because this happens, I am using the sma 38.i am using avco method of accounting , I also uploaded the product by csv at no cost and in the purchase with cost and the cost of the product does not appear in the list of products, in settings it is configured to update the cost with the Purchase.
