• What is the cause and solution for SAP error message CX895 - Class &1 and/or class type &2 cannot be changed ?

  The SAP error message CX895 indicates that there is an attempt to change a class or class type that is not allowed. This typically occurs in the context of object-oriented programming in ABAP when you try to modify a class that is either locked, not editable, or has certain restrictions applied to it.
  Causes:
  
  Class Locking: The class you are trying to change may be locked by another user or process.
  Transport Request: The class might be part of a transport request that is currently being processed, preventing changes.
  Class Type Restrictions: Certain class types (like interfaces or abstract classes) may have restrictions on modifications.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the class.
  System Settings: The system may be configured to prevent changes to certain classes or types for stability or security reasons.
  
  Solutions:
  
  Check Locks: Use transaction code SM12 to check if the class is locked by another user. If it is, you may need to wait until the lock is released or contact the user who has locked it.
  Transport Request: Verify if the class is part of an active transport request using transaction code SE09 or SE10. If it is, you may need to wait until the transport is completed.
  Review Class Type: Ensure that you are not trying to change a class type that has restrictions. If it’s an interface or abstract class, check the documentation for any limitations.
  Check Authorizations: Ensure that your user role has the necessary authorizations to modify the class. You can check this with your SAP security team.
  System Configuration: Consult with your SAP Basis team to see if there are any system settings that prevent changes to certain classes or types.
