I want to import vendor-pricelist with vendor-variant. I download import-template for import-page, and added 1 column form with label 'Vendor Variant'. For the value I get it from vendor-variant-field on vendor-pricelist-form. It show product-name with its attributes ( eg. 'iMac (White)' and 'iMac (Black)' ).
But it never success, I get an error " No matching record found for name 'xxxx' in field 'Product Variant ". 

What actually should I put on that column?
I know that product.product have no 'name'-field, so I tried to manipulate the code by inheriting product.product. I add 'complete_name' field with 'compute'-function for reading 'name_get'-function, and set 'complete_name as '_rec_name', but still nothing happened.
