Field help (POHBPTNUM) 

This is the carrier in charge of transporting the goods. It is initialized to the supplier's carrier entered in the order header. A selection window is used to choose another carrier. It is also possible to access the carrier table if the user's authorizations allow it.

Inter-company specificities: In the case of an inter-company or inter-site order, the carrier entered in the generated sales order is initialized to the carrier from the ship-to customer and not by the information entered at this level (except if the carrier has not been entered in the ship-to customer).
