Hi,
Okay I see.
The CSV import is pretty strict on the column names ; so if you rename a column that HikaShop does not know, it will ignore it.
So you can rename "product_id" column otherwise HikaShop won't be able to know the product id.
But like I told you, you can add new columns ; HikaShop would skip them (and might generate you a warning message telling you that the column "...." is unknown).
Kind regards,
