Unique Identification of Handling Units (SAP Library - Handling Unit Management (LO-HU))

Unique Identification of Handling Units

Use

Since a handling unit is a physical unit of packaging materials (load carrier / packaging material) and the goods contained therein, each handling unit must be clearly identifiable. This unique identification is made by using an identification number. The uniqueness of this identification number can be guaranteed within one client by using a number range object. You can only ensure that the identification number is unique system-wide if you assign an SSCC18.

Prerequisites

If you want to use the HU function outside of delivery processing, you must make the following settings in the Implementation Guide (IMG) for Handling Unit Management in the External Identification section:

To ensure unique number assignment, select the Set Unique Number Assignment for HU Identification activity and set the HU ID unique indicator.

To set the type of number assignment, choose the Define Number Assignment for Each Packaging Material Type activity.

To set number assignment for HU identification by using a number range interval, choose the Number Range Maintenance for HU Identification activity.

If you want to ensure a unique identification system-wide, use the activities in the SSCC Generation Acc. to EAN128 section.

Note

In contrast to the number range object for handling units, make sure that the SSCC number is 18 characters long. If you activate system-wide SSCC number assignment, you must execute the Define Number Ranges activity, which can be found under Storage Units ® Master Data in the Implementation Guide (IMG) for Warehouse Management. Then, set the length of the SU numbers to 18 characters in the Conversion exit for storage unit number step of this activity.

Example

If you want to process or display a specific handling unit, you can only select that particular handling unit if its identification only appears once in the system. If you allow the same handling unit identification to be assigned several times, the system cannot determine which handling unit you want to process. In such a case, scanner-based processing would not be possible.
