Sage X3 has an important feature to allow the counting of stock. The Stock be counted is the screen which allows the user to check the inventory which shows the list of stock which are counted.
Functional Path: Inventory àCounts àStock being counted.
This function is used to list the products in the process of a stock count for a site, for a given range of products. Only the products present in the stock count list and therefore where the count has not yet been validated are presented in this inquiry.
Select the site and insert the range of the product and click on search it will give the stock of products which is not validated yet.
