Mike, what is the purpose of a SKU number?
Why do companies use SKU numbers?
To cross reference and pull inventory items.
It's pretty simple, when you think about it, and every company with any decent size warehouse, uses SKU's.
So, eBay and Auctiva allow us to enter SKU's when we list items. Giving us back the variation name, without the SKU, is kinda like telling someone to go out to the warehouse and grab a White Tshirt, with the Sleeping Puppy logo on it, in White, of a size Large...and make sure it's long sleeved. When it would be a whole lot easier to say "Go pull Sku: 39127".
I hope this clarifies things such that you're not confused any longer. I'm sorry to see that your programmers added the variation detail, without the SKU.
