I will try to explain a working example of this requirement. Many years ago we were selling widgets and at the volume we were selling we stocked them as Eaches. After many years the popularity of the product increased and the volume of goods going in and out of the warehouse has increased. So now the vendor sells it to us in Boxes (1 Box = 10 Each). But we still have to count the goods on the shelf one at a time. It would be preferred to crate an entry somewhere that indicates a choice was made that as-of a point in time, the inventory unit changed. If inventory has to be removed from the system to make the change then OK. The confusion of "what does an Each represent?" as one widget or a box of widgets results in handling the wrong quantity.This would improve the ability of an organization to adjust to the changing needs of a product without having to create a duplicate released product. This would also allow fixing a mistake where the product was created with the wrong unit. I understand why this capability was removed when D365 was released, but we should revisit the impact this decision is having on organizations and the physical handling of goods in the warehouses.
