Can I create and sale an item X which is composed with 3 differents other items A, B and C ?
There is not stock of item X it is only used to be placed in an order with its specific price.
Items A, B and C can be sold independendly. Their are finished goods like item X.
The difference is that item X is a "copacking" finished good which exists only when there's orders placed on this item.
Preparation and shipment of an order with the copacking item X generate movement only on the A, B and C items.
