This error typically arises in the context of SAP Extended Warehouse Management (EWM) when there is a problem with the handling unit's status, configuration, or data integrity.
  Cause
  The error can be caused by several factors, including:

  Data Integrity Issues: There may be inconsistencies or missing data related to the handling unit, such as missing master data or incorrect configuration settings.
  
  
  Duplicate Handling Unit Reference: The handling unit reference you are trying to add may already exist in the system, leading to a conflict.
  
  
  Authorization Issues: The user may not have the necessary permissions to perform the action related to the handling unit.
  
  
  System Configuration: There may be configuration settings in EWM that restrict the addition of certain handling units based on specific criteria.
  
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Handling Unit Status: Verify the status of the handling unit (HU &2). Ensure that it is not locked or in a status that prevents it from being added to the reference table.

  Consult Configuration Settings: Review the EWM configuration settings to ensure that there are no restrictions preventing the addition of the handling unit reference. This may involve checking the handling unit management settings.
  
  
  Debugging: If the issue persists, consider using transaction codes like /SCWM/PRDIAG or /SCWM/PRD to analyze the handling unit and its references further. You may also want to check the application logs for more detailed error messages.
