hi,
Can anyone explain me briefly about "Preliminary Leg" and "Subsequent Leg" while carrying out ROUTE DETERMINATION.

Stage actually refers to the information about the geographical factors of a shipment. Any shipment can have 3 types of stages - Legs, Load Transfer Point and Border Crossing Point.
A shipment can have any one or all 3 or any combination of the stages.
Leg - Refers to the Starting point and Ending point of a shipment. Could also include any intermediate points (Destinations)
For eg. : Assume there are two deliveries (D1 and D2) in a shipment.
D1 : From A - B
D2 : From C - D
Now the legs will typically be
A - B (D1 is assigned)
B - C (Empty leg - No deliveries)
C - D (D2 is assigned)
There are different types of legs available
1. Direct leg
2. Preliminary Leg
3. Main Leg
4. Subsequent Leg
5. Return Leg
In the example above, all legs are "Direct Legs".
If a shipment goes from Bangalore to Palo Alto Via Mumbai and San Fransisco then
Bangalore - Mumbai (Via Road / Rail) - Preliminary Leg
Mumbai - SFO (Via Sea / Air) - Main Leg
SFO - Palo Alto (Via Road) - Subsequent Leg
Off the above 3 legs, Mumbai could be a Load Transfer Point (The point where a shipment is unloaded from one MOT and loaded onto another).

Example of a transportation chain:
The computer manufacturer ships deliveries from Dresden and Hamburg to Boston and
Philadelphia:
The deliveries from Dresden and Hamburg are shipped separately by truck or rail to Rotterdam:
Leg indicator 1 = Preliminary leg
In Rotterdam, the deliveries are loaded together and shipped to New York:
Leg indicator 2 = Main leg
In New York, the deliveries are again shipped separately by truck to Boston and by rail to Philadelphia:
Leg indicator 3 = Subsequent leg
I hope this example helps

Jitesh
