Not sure if anyone in the community has faced this. I have created a configurable product that has 5 variations . the configuration works great and the simple boxes are made just fine after I finish with the setup of the configurable box. now if I want to add a value option of one of the attributes i get the new products showing undefined.
Let's say i have product variation color and when I created the configurable product i had 3 colors, red , blue and orange. and let's say my base sku for the configurable products is BASE.
So when I create the configurable product, magento creates the simple products BASE-blue, BASE-red, and BASE-orange.
Now let's say I decided to add a new variation value for variation color, and its purple, so I go to the attribute, add purple, save, go to the configurable product, edit the configuration, add purple to the variable configuration, then once I finish the configuration dialog, magento says i'm making new simple product Undefined-purple, instead of BASE-purple. How can this issue be fixed ?
