When defining a single BOM for a product template having multiple product variants, we can have different components where the lot number must be propagated for different product variants. Therefore we need to allow to mark multiple BOM line with propagate_lot_number, and to avoid complicating the check function on the BOM lines, we ensure at the manufacturing order confirmation that only a single component is set to propagate its lot number.
