Opencart do not assign unique SKU to each option of a product. For example, if one product has multiple options (sizes & color), then you cannot update the inventory of each option directly. You have to enter/scan product SKU, then select one option from option list. To remove this option selection step, we have developed a module (Opencart Option SKU Manager) to assign unique SKU to each option of product. After installing this module, you can directly enter/scan the SKU of option of SKU and update the quantity.
