ATTENTION : This multiple barcode only works if you want to use it on the POS. As a matter of fact, it won’t work if you want to use it with the barcode app (operations / inventory adjustment / batch transfer).

Activate your DEBUG mode.

1. Set up a barcode (the one of a supplier or your own if you have one) on the barcode field from the product.template model. 

1. Activate the barcode scanner configuration in the inventory app. 

1. Go in the configuration of the inventory app > Barcode nomenclature > select the “default nomenclature” set in the barcode scanner configuration > click on “add a line”.

1. Indicate 

1. a name of your choice. 

2. Start the sequence with “1”, then add +1 for each new line that you add.

3. Set the “Alias” type

4. Set the barcode of another supplier for the product

5. Set the barcode that is set on the product.template so Odoo can make the link with the two barcodes.

For every barcode that you have, you should create a new rule but it can be imported on the barcode.nomenclature model.
