Online meeting with Calvin over a Zoom session. We talked about tracking inventory to a sub level. Not just sub inventory, but sub inventory and moving it between smaller holding areas. Basically, sub inventory with multiple sub locations per batch and/or per group or lot. Not impossible, but definitely a full lever deeper than just plain sub inventory. We went over a few ideas and also some pros and cons of the current options. We decided to push it off and try to tackle it later on.
