I list to multiple selling platforms which have different requirements for the product identifiers, however, when listing from Linnworks I can only work with the one barcode field. The result of this is that I can not list to all of my selling platforms through Linnworks this way.
In addition to the Barcode field in Product Details, there are two other ways to add Product Identifiers to your inventory items, which can then be mapped accordingly in your eBay configurations for listing creation:
Mapping the correct field
Once you have added the needed Product Identifiers to your items with one of the above methods, you can specify in the eBay Configurator Main settings which value the Barcodes should be taken from. This field is specific to each configurator, so each marketplace can have its own barcode field specified separately.
When there is no Extended Property specified in this field or if the specified Extended Property does not exist on the item you are listing, the value will automatically be taken from the Barcode field in Inventory > My Inventory > (click on the SKU) Product Details > General tab > Barcode field.
a) If you choose to use Linnworks Product Identifiers for the barcode values, the Extended Property for barcode should be mapped with a value from the list that starts with ProductIdentifier. e.g. ProductIdentifier.EAN.
b) If you choose to use Extended Properties, the Extended Property for barcode should be mapped with the name of the respective Extended Property name you have added to your inventory items.
