a. The country and the Departure Zone of the shipping point +
b. Shipping Conditions agreed in the sales document type or with the sold to party +
c. Transportation Group assigned to the material +
d. The country & Transportation Zone of the ship to party (in CMR)
Route can be manually overwritten during a sales order processing. You can re-determine the route in the outbound delivery based on weight (weight group) provided it is allowed in the configuration of the delivery type.
Scheduling takes into account the following times – 
a. Transit Time + 
b. Loading Time + 
c. Pick/Pack Time + 
d. Transportation Lead/Planning Time. 
The loading time and pick/pack time come from the shipping point whereas the transit time and transportation lead time come from the route.
The system performs backward scheduling first to confirm the required quantity checking the material availability on the material availability date. If the material availability date or the transportation planning date falls before the order date, the system automatically carries out forward scheduling and will propose a future date. A delivery type can be customized to carry out rescheduling if required during the delivery processing.
