I need to create these items: Luggage Set : They come 1 small- 1 medium- 1 large on every set. I need to order set and sell either sets or pieces. I tried setting the set as a parent and the pieces as childs but I am having problem with the inventory. When I order a set the qty for small-medium-large should increase 1 for each one, when I sell a set, qty for small-medium-large should decrease 1 for each one If I sell a medium luggage the qty for that piece should decrease, not the qty for the set. I do not need to reorder by piece, only by sets.
Can somebody help me on this matter??
