My company needs to manage raw materials by Kg/lb. by lots. We order and consume the raw materials (via Manufacturing Orders) by that UoM. The issue is that we obviously store the raw materials by drum/tote. We need tractability for each lot and sometimes drum or raw material. Is there way to put lbs of raw materials in a container and still manage them by the UOM and have it function with lots? 

We have tried the product packaging, but it doesn't seem to work very well with products traced by lots. Thank you for the help.

Edit: Using Odoo 13.0+e (Enterprise Edition)
