  Cause:
  This error message indicates that there is an attempt to delete a class associated with a specific expression, but the deletion cannot be completed. Common causes for this error include:
  
  Dependencies: The class or expression you are trying to delete may be in use or referenced by other objects, preventing its deletion.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Dependencies: 
  
  Investigate if the class or expression is being used elsewhere in the system. You can use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check for dependencies.
  If the class is referenced in other configurations, you will need to remove those references before attempting to delete it.

  Data Integrity Checks:
  
  Review any data integrity constraints that may be preventing the deletion. You may need to consult with your technical team or SAP support to understand these constraints better.
