issue: We want to store a single product, in multiple locations, with the same lot number

version: Odoo Community 11.0 hosted on AWS

details:

1. From a confirmed Purchase Order we have a Delivery in the Inventory app/module

2. A batch of the delivery is the same product and same lot number as already existing stock

3. Due to space considerations we need to store the new delivery in a different location of our warehouse

4. When we are adding the details of the delivery under the Detailed Operations tab (by filling out the 'Done' and 'Lot/Serial Number') there is no issue.

5. When we go to Validate, we get the error 'The combination of serial number and product number must be unique !'

What we have tried:

I found the documentation page: https://www.odoo.com/documentation/user/11.0/inventory/management/lots_serial_numbers/lots.html

However this page shows options that I don't see when I navigate to Configuration-Settings-Inventory.  I only see a checkbox for Traceability: 'Lots and Serial Numbers'

I need for Odoo to let me put to different batches of the same product, with same lot numbers, in a different location.  Any help or insight given would be greatly helpful.
