Carrier and Warehouse maping

Hi Gurus,

My Client us in JD edwards and moving to SAP.We have this scenario.We maintain some warehouses near the ports . After we get an order, we check the inventory in the warehouse . If inventory is available, We basically ask carriers to give freight rates to move the inventory . Inventory is ireleased from the warehouse and the ocean carrier delivers the freight to the final destination.

Could you please help me in this
