• What is the cause and solution for SAP error message CL002 - Class type &: & & already created ?

  The SAP error message CL002 indicates that a class type (in this case, a class of type &) has already been created in the system. This error typically occurs when you attempt to create a class that already exists, which is not allowed in SAP.
  Cause:
  
  Duplicate Class Creation: The most common cause of this error is that you are trying to create a class with a name that already exists in the system.
  Incorrect Class Type: The class type you are trying to create may not be valid or may not be the intended type.
  Namespace Issues: If you are working in a specific namespace, ensure that the class name adheres to the naming conventions and does not conflict with existing classes.
  
  Solution:
  
  Check Existing Classes: Before creating a new class, check if a class with the same name already exists. You can do this by using transaction code SE80 (Object Navigator) or SE24 (Class Builder) to search for the class.
  Use a Different Name: If a class with the same name exists, consider using a different name for your new class to avoid conflicts.
  Review Class Type: Ensure that you are using the correct class type and that it is appropriate for your needs.
  Namespace Management: If you are working in a custom namespace, ensure that your class name is unique within that namespace.
