I have never tested before creating FBA and MFN offer in one flat file. Currently, I create MFN and next every product I copy or transfer to FBA manually. I am looking for the most efficient way to add products using only one Flat File.

I found something like that (for FBA):

In your Template file, set the quantity field as blank. Set the Fulfilment Centre ID field to AMAZON_EU. Complete the ‘Is this product a battery or does it utilize batteries?’ field with the appropriate value Complete the ‘Applicable Dangerous Goods Regulations’ field with the appropriate value

So I have one product for 2 channels

MY-SKU

FBA-MY-SKU

If I put them together in one file with the same EAN, will it make errors?

It would be perfect to have them in one Parent Node.

Any ideas?
