Hi, i am using odoo11.

I am importing some data from a legacy db, including products and lots. I activated the lot traceability from the general settings.

When importing products, i set a field as the 'external ID', like so:

External ID: C; Name: Cucumber; ... etc ...

When i import lots, i suppose the correct way is to setup the fields like this:

Product: C; Lot number: 111222333; ... etc ...

but this also seem to work:

Product / External ID: C; Lot number: 111222333; ... etc ...

Are both ways equivalent? If not, what is the correct way to proceed in this case?

Thank you very much
