  Cause:
  
  Missing Class Definition: The specified class (indicated by &1) has not been created or activated in the ABAP system.
  Incorrect Class Name: There may be a typo or incorrect naming in the code that references the class.
  Transport Issues: If the class was recently transported from another system, it may not have been successfully imported or activated.
  Namespace Issues: The class might be in a different namespace that is not accessible in the current context.
  Authorization Issues: The user may not have the necessary authorizations to access the class.
  
  Solution:
  
  Check Class Existence: Use transaction code SE24 (Class Builder) to check if the class exists. If it does not, you may need to create it.
  Correct Naming: Verify the spelling and case of the class name in your code. ABAP is case-sensitive, so ensure that the name matches exactly.

  Namespace Verification: Ensure that the class is in the correct namespace and that your program has access to it.
  Authorization Check: Ensure that the user has the necessary authorizations to access the class. You can check this in transaction SU53 after the error occurs.
