  System Configuration: The system may be configured to treat certain HUs as internal based on specific criteria or settings.
  HU Status: The status of the HU may not allow it to be assigned externally due to its current state (e.g., it may be locked, in use, or in a specific process).
  
  Solution:
  
  
  Check HU Status: Verify the status of the HU in the system. You can do this by using transaction codes like /SCWM/HU or /SCWM/PR to view the details of the HU. Ensure that it is not locked or in a state that prevents external assignment.

Ensure that the HU type is set up correctly and that it is intended for external use if that is your requirement.
  
  
  Use a Different HU: If the HU is indeed internal and cannot be changed, consider using a different HU that is designated for external assignments.
