I have configurable products that have simple products and they are configurable by two attributes - posters with size and frame. I am adding new products that represent new frames and sizes which are created ok, but I want them to attach to a certain configurable product.
Example:
I have a configurable product - poster with this simple products
Wood frame - 30x30cm
Aluminum frame - 50x50cm
Aluminum frame - 70x50cm
I generate
Wood 50 x 50cm
Aluminum 100x100cm
How can I do that?
