 <p>So I have made so headway.<br> I started experimenting. <br> First if Magmi's Attribute Set Importer v0.0.2 was set ON - it would error and create 26 empty attributes no matter what I did.<br> Next it turns out you can not create and use custom attribute <B>product_id.</B> This also causes errors. I deleted that and changed it to manufacturer_id and it imports correctly.</p> <p>Here is the header I have so far:</p> <pre><code>sku name _attribute_set root_category_id weight description short_description categories _type status visibility manage_stock tax_class_id price cost qty manufacturer vendor color upc manufacturer_id </code></pre> <p>Here is example data:</p> <pre><code> 400100433072 Daewon Song Gold and Purple Default 2 0.25 Daewon Song Gold and Purple ear buds ear buds accessories::1::0::1/earbuds::1::0::0 simple 1 4 1 2 21.99 10 1 LOUD HAPPY HOUR gold purple 400100433072 02-02-0009 </code></pre> <p>Will just have to figure out how to deal with new attributes... </p>
