Martins, if you are truly going to use a work order because you need to tracking labor and machine work center costs, then you can generate the work order directly from the sales order and allocate accordingly.  If you do not need to capture labor and machine costs, then perhaps you should consider a sales kit.

That is not possible, this happens with this business logic that customer selects the components before deciding the final art of the final product... Natural stone business... I think we need to extend the customer allocation object, to make it detailed instead of global only...
