• What is the cause and solution for SAP error message RJ061 - Class &1 does not implement interface &2 ?

  The SAP error message RJ061 indicates that a class does not implement a specified interface. This error typically arises in the context of ABAP programming when a class is expected to implement certain methods defined in an interface, but it fails to do so.
  Cause:
  
  Missing Implementation: The class defined does not implement all the methods specified in the interface.
  Incorrect Class Declaration: The class may not be correctly declared to implement the interface.
  Changes in Interface: If the interface has been modified (e.g., methods added), the implementing class may not have been updated accordingly.
  Typographical Errors: There may be typographical errors in the class or interface names.
  
  Solution:
  
  
  Check Class Implementation:
  
  Open the class in the ABAP Workbench (SE80 or SE24).
  Verify that the class implements all the methods defined in the interface. If any methods are missing, implement them.
  
  
  
  Check Interface Declaration:
  
  
  Ensure that the class is correctly declared to implement the interface. This can be done in the class definition section.
  
  
  Example:
  INTERFACE if_example.
    METHODS method1.
  ENDINTERFACE.
  
  CLASS cl_example DEFINITION
    INHERITING FROM if_example
    ...
  ENDCLASS.
  
  
  
  
  Update Class:
  
  If the interface has changed, update the class to implement any new methods that have been added to the interface.
  
  
  
  Check for Typos:
  
  Double-check the names of the class and interface for any typographical errors.
  
  
  
  Activate Changes:
  
  After making the necessary changes, ensure that you activate both the interface and the class.
  
  
  
  Related Information:
  
  ABAP Workbench: Use transaction codes SE80 (Object Navigator) or SE24 (Class Builder) to navigate and edit classes and interfaces.
  Documentation: Refer to SAP documentation for guidelines on implementing interfaces in ABAP.
  Debugging: If the error persists, consider using debugging tools to trace where the implementation is failing.
  
  By following these steps, you should be able to resolve the RJ061 error and ensure that your class correctly implements the specified interface.
