Hi,
Unfortunately, there is no column "fee_type" in the hikashop_product table so I understand your error message.
The HikaMarket fee rules are stored in the table "#__hikamarket_fee".
That table have a field "fee_type" for the kind of target (the configuration, a vendor, a product...) and a "fee_target_id" for the ID of the targeted element.
If you want to import some fee rules for a specific product, I'm afraid that you will have to import it directly in the database.
The HikaShop import system does not allow third party components to plug events into ; so HikaMarket can't handle a special "fee_type" field to perform such kind of import in the "hikamarket_fee" table.
It would require a specific development in HikaShop for a refactoring of the import system, so components like HikaMarket would be able to handle new specific data and import their own elements.
Currently, only the "product_vendor_id" is available : that field was already in the HikaShop schema (and HikaMarket was the first component to really use it).
Regards,
