Amazon error 8098: Invalid fulfillment channel or fulfilment centre valueThe fulfillment-center-id / fulfillment_channel value is not one Amazon recognises, or it conflicts with how the SKU is currently fulfilled - for example sending a merchant quantity for a SKU that is enrolled in FBA.How to fix error 8098

For merchant-fulfilled inventory leave fulfillment-center-id as DEFAULT.

For FBA use AMAZON_NA (or the correct regional value) and leave quantity blank - FBA quantity is controlled by what is in the warehouse, not by your feed.

Do not mix FBA and merchant rows for the same SKU in one file.

If you are converting a SKU between FBA and merchant-fulfilled, do the conversion in Seller Central first, then resume feed updates.
