Christian, While the scenario presented by Jacopo is a surely a potentially unexpected nice-to-have feature in the feature set of OFBiz, you should ask yourself if that is something that you want in your manufacturing processes.
Manufacturing processes are sets of controlled actions with predictable outcomes. When you are about to manufacture 100 units of your end product you would not want more than the required quantities of your components based on your BoMs. Anything issued more than required will cause extra actions like returning the surplus back to inventory, creating an extra end product (the tortilla as Jacopo outlined) that has not been ordered and might get stale in inventory, or even scrapping it due to quality degradation issues of the component. Anything issued less than required will delay the production run with potentially endangering the quality of the end product. Another aspect that you need to take into consideration is the cost of manufacturing involved. Your production run will lead to a cost of manufacturing that is based on (and in line with) the calculations made up front. When registering an extra (different) end product (again the tortilla) what would the effect be on the cost of manufacturing of both the intended end product and the extra?
