I am seeking for a solution regarding selling products in webshop in Odoo V8.

The product template is having multiple variants lets say, 

1.    Color : Black and Silver 
2.    Size : Large, Medium and Small

This will generate total 6 product variants from cross multiplication.

Now, how can I deactivate(unpublish) any one of these product variants from webshop? 

For example : I dont want to publish the product variant - Black color with Medium size. ( Assume that I made a too much sales earlier but now Black Color with Medium size is not available from my supplier indeed, so obviously I don't want to show in website. Because that variant is gonna to have no more sales. )

One of the solution I can see is to uncheck ( Deactivate ) the 'active' field. 

But by doing so it will also not be visible from backend. So I can't see this product in Sales Reports or somewhere else in backend.

Can any one suggest me a favourable solution please ??
