This is a system restriction because certain UOMs are critical for operational processes and cannot be deleted.
  Cause:
  
  UOM Usage: The UOM you are trying to delete is being used in various transactions or master data related to distance or time measurements. For example, UOMs like kilometers, miles, hours, etc., are often tied to logistics processes and cannot be removed.
  System Restrictions: SAP has built-in restrictions to prevent the deletion of UOMs that are essential for calculations and processes, ensuring data integrity and operational continuity.
  
  Solution:
  
  
  Check Usage: Before attempting to delete a UOM, check if it is being used in any active transactions, master data, or configuration settings. You can do this by:
  
  Reviewing the relevant master data (e.g., material master, service master).
  Checking any open or historical documents that may reference the UOM.
  
  
  
  Change UOM: If the UOM is in use, consider changing it instead of deleting it. You can update the relevant records to use a different UOM that is not restricted.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on managing UOMs in EWM. This can provide insights into best practices and alternative approaches.
  
  
  Contact SAP Support: If you believe the UOM should be deletable or if you encounter issues that cannot be resolved through standard procedures, consider reaching out to SAP support for assistance.
  
  
  Related Information:
