Unique Identification of
Handling Units 
Use
Since a handling unit is a physical unit consisting of packaging materials (load carriers/packing material) and the goods contained on/in it, each handling unit must be uniquely identifiable. You can do this by assigning an identification number. Within a client, this uniqueness can be ensured using a number range object. Across systems, unique identification is only possible by assigning a SSCC18 .
Prerequisites
Ensure that you have made the following Customizing settings:
1. To configure the type of number assignment, choose the IMG activity Assign Number Range Intervals to Packaging Material Types.
2. To configure number assignment of the HU identification using a number range interval, choose the IMG activity Maintain Number Range Intervals for HU Identification.
3. If you want to ensure unique identification across systems, choose the IMG activities in the section SSCC Number Assignment According to EAN128.
