• What is the cause and solution for SAP error message BSP_WD000 - Redefinition of method CONNECT_NODES() is missing in class &1 ?

  The SAP error message BSP_WD000 Redefinition of method CONNECT_NODES() is missing in class &1 typically occurs in the context of Web Dynpro ABAP development. This error indicates that there is a method CONNECT_NODES() that is expected to be redefined in a subclass, but it is missing.
  Cause:
  
  Inheritance Issue: The error usually arises when a subclass is expected to override a method from its superclass, but the method is not defined in the subclass.
  Changes in Superclass: If the superclass has been modified (e.g., the method was added or changed), and the subclass has not been updated accordingly, this error can occur.
  Incorrect Class Implementation: The class that is supposed to implement the method may not have been properly defined or activated.
  
  Solution:
  
  
  Check Class Definition: Go to the class indicated in the error message (replace &1 with the actual class name) and check if the CONNECT_NODES() method is defined. If it is not, you need to implement it in the subclass.
  
  
  Redefine the Method: If the method is missing in the subclass, you can redefine it by:
  
  Opening the subclass in the ABAP Workbench (SE80 or SE24).
  Implementing the CONNECT_NODES() method according to the requirements of your application.
  
  
  
  Activate the Class: After making changes, ensure that you activate both the superclass and the subclass to reflect the changes.
  
  
  Check for Inheritance: Ensure that the subclass is correctly inheriting from the superclass. You can check this in the class attributes.
  
  
  Review Documentation: If you are unsure about the implementation details of CONNECT_NODES(), refer to the documentation or the superclass implementation to understand what the method should do.
  
  
  Debugging: If the issue persists, consider debugging the application to trace where the method call is made and ensure that the correct class is being used.
