  Cause:
  
  Number Range Conflict: The system is trying to create or assign a Handling Unit ID that conflicts with an existing number in the predefined number range. This can happen if the number range is not properly configured or if there are overlapping ranges.
  Manual Entry: If a user manually enters a Handling Unit ID that falls within a reserved or predefined range, it can lead to this error.
  Configuration Issues: The configuration of the Handling Unit management in the system may not be set up correctly, leading to conflicts in number assignment.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the configuration for the Handling Unit number range.
  Ensure that the number range is correctly defined and does not overlap with other ranges.
  
  
  
  Review Handling Unit Creation Process:
  
  Ensure that the process for creating Handling Units is being followed correctly. If the system is set to automatically generate HU IDs, make sure that the settings are correct.
  
  
  
  Adjust Manual Entry:
  
  If the error is due to manual entry, ensure that users are aware of the predefined number ranges and are not entering IDs that conflict with these ranges.
  
  
  
  Check for Custom Code:
  
  If there are any custom developments or enhancements in the system that affect Handling Unit creation, review them to ensure they are not causing the issue.
