Individual product sales report including variations

I cannot believe a year after creating my websites, it's now time to work out what items including variations have sold, so I know how much stock to order for the coming year, and I cannot get a simple sales report for each product, including variations. It's actually the one thing I never thought I'd have an issue getting, so didn't think to check. I am now tempted to move my websites away from Deco, after a year of hard work!
