  Cause:
  The error occurs because the certificate you are attempting to delete is linked to one or more materials that are still active in the system. SAP enforces this restriction to maintain data integrity and ensure that all references to the certificate are properly managed.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Active Materials: 
  
  Use transaction codes like MM03 (Display Material) or MM02 (Change Material) to check which materials are currently assigned to the certificate you want to delete.
  You can also use reports or queries to list all materials associated with the certificate.
  
  
  
  Remove Certificate Assignment:
  
  For each active material that is linked to the certificate, you will need to remove the certificate assignment. This can typically be done in the material master record under the relevant views (e.g., Basic Data, Quality Management).
  Navigate to the material master record and go to the Quality Management view. Remove the certificate assignment from the materials.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or references to the certificate in other areas of the system, such as inspection plans, quality notifications, or batch records.
  
  
  
  Delete the Certificate:
  
  Once all active materials have been disassociated from the certificate, you should be able to delete the certificate without encountering the error.
  
  
  
  Testing:
  
  After deletion, it’s a good practice to test the system to ensure that everything is functioning correctly and that there are no lingering references to the deleted certificate.
