  To resolve this error, you can follow these steps:
  
  
  Identify Usage:

  Going to the classification view of the relevant categories and removing the ID type from the category.
  Ensure that no objects (like materials, documents, etc.) are still linked to the ID type.
  
  
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or references to the ID type in other configurations or settings within the system.
