in Sales and Warehouse you have a view Products by Categorie. by default there exist All and All/Saleable. Inside of the product Form View the Internal Categorie [categ_id] where these relate to appears in the Accounting tab.
I wonder what this Categorie is meant to do. At firs I would imagine it is meant to divide products in to logical groups such as Components, Ready made products, etc. But the fact this Internal Categorie field is located in the Accounting tab implies that this is more related to what financial kind of product it is. Not so much an organizational Category from a "warehouse perspective'
Can somebody explain to us, how the Internal Categorie [categ_id] is supposed to be used?
