Export-Import Advanced prices missing product mapping

Greetinds, I would like to export (and later reimport) some advanced priced for product variants, but in the exported csv it is hard to identify which price belongs to which products, because there is only 3 columns of ID codes. Anyone could advice me please which field should I map in order to see also the product number, product name, categories and the manufacturer?

Thank you very much in advance for your tips and help!
