Example: Stock Transport Order 
You have specified a material in the following plants:
Plant | Segmentation Enabled | Company Code |
|---|---|---|
DC1 | Yes | 001 |
DC2 | No | 001 |
DC3 | Yes | 002 |
Scope is maintained as Both Requirement and Stock Segment Maintained in the segmentation strategy
Scenario 1: DC3 supplies to DC1. Both the supplying plant and the receiving plant are relevant for segmentation. You defined the stock segment in the stock transport order. The system determines the requirement segment in one of the following ways:
Priority 1: Based on the segment value assignment you define in Customizing for Stock Transfer under
Logistics – General 
Segmentation Define Segmentation Strategies 
.Priority 2: If you do not define the segment value assignment in Customizing activity Define Segmentation Strategies, the system determines the requirement segment based on the logic you define in the BAdI BADI_SEG_SPEC_PROD_MM (under
Logistics - General Segmentation Enhancements for Segmentation ).Priority 3: If you do not specify the logic in the BAdI, the system determines the requirement segment based on the default stock segment you define in Customizing for Define Segmentation Structures under
Logistics – General Segmentation .Priority 4: If BLANK is not a valid segmentation value and no segmentation value is found, the system displays an error message.
Scenario 2: DC3 supplies to DC2. The receiving plant is not relevant for segmentation. You did not define the stock segment in the stock transport order. The system determines the requirement segment in one of the following ways:
Priority 1: Based on the segment value assignment maintained in Customizing for Define Requirement Segment for Supplying Plants under
Logistics – General Segmentation .Priority 2: If you do not specify the segment value assignment in Customizing activity Define Requirement Segment for Supplying Plants, the system determines the requirement segment based on the default stock segment you define in Customizing for Define Segmentation Structures under
Logistics – General Segmentation .Priority 3: If BLANK is not a valid segmentation value and no segmentation value is found, the system displays an error message.
Scenario 3: DC2 supplies to DC1. The supplying plant is not relevant for segmentation. You define the stock segment in the stock transport order. As the supplying plant is not relevant for segmentation, the system does not determine the requirement segment and the material is posted.
The following image illustrates the transfer of stock between plants with different segmentation strategies:
Scope is maintained as Only Requirement Segment is Maintained in the segmentation strategy
Scenario 5: DC3 supplies to DC1. Both the supplying plant and the receiving plant are relevant for segmentation. However, as the scope is Only Requirement Segment is Maintained in the segmentation strategy, you do not define the stock segment. The system determines the requirement segment based on the segment value assignment you define in Customizing for Define Requirement Segment for Supplying Plants under Logistics – General Segmentation .
The following image illustrates the transfer of stock between plants with different segmentation strategies:
