Leg Determination Categories 
Use
The basic procedures are described in Automatic Leg Determination.
Prerequisites
In the Customizing application, you can define for the shipment type (Parameters for ‘Determine legs’) how leg determination should be carried out.
You can also display this information on the overview screen of the shipment document (Control tab).
Features
The SAP system supports the following categories of leg determination:
● Leg determination ‘_’ (blank):
The system does not perform leg determination.
● Leg determination ‘0’:
The system does not perform leg determination, but the assignment of deliveries to stages is determined. (See also Automatic Assignment of Deliveries.)
● Leg determination ‘1’
Legs are determined according to the itinerary (order of deliveries) in the shipment document.
This type of leg determination is used for collective shipments in which the goods are picked up at individual shipping points in a certain order and then delivered to individual ship-to parties in a certain order.
● Leg determination ‘2’
A type of leg determination in which a preliminary leg is created for each starting point and a subsequent leg is created for each destination point.
This type of leg determination is used for transporting deliveries that are to be sent by sea in a group, but originate from different shipping points or are to be transported to different ship-to parties.
● Leg determination ‘3’
A type of leg determination in which a preliminary leg and a subsequent leg are created for each delivery.
This leg determination type is used for transporting extensive amounts of goods that must be distributed among multiple deliveries because one delivery would not offer enough capacity.
● Leg determination ‘4’
This type of leg determination is similar to type ‘1’ except that shipment types for preliminary and subsequent legs (which you can enter in the shipment header) are taken into consideration. This way you can suppress certain preliminary or subsequent legs.
Each type of leg determination is described in detail in the following sections:
Category 1: According to the Itinerary
Category 2: Preliminary/Subsequent Leg for Point of Departure/Destination
Category 3: Preliminary and Subsequent Leg for Each Delivery
Category 4: With Shipping Type for Preliminary Leg and Subsequent Leg
