Hi muk_t, this is the situation: in store we have very much configurable product created with this structure:
- structure - colors - bulbs
We want reduce the tructure on only two super attribute: - colors - bulbs If, I disable to use the attribute "structure" for configurable products this not change exists product, but I can create new product with two attribute. The problem is remove the attribute "structure" from old product.
One of my test, on a copy of site, I removed it directly from MySQL database, in catalog_product_super_attribute table but ths solution don't like me.
There is another method more clean to remove this attribute?
