• What is the cause and solution for SAP error message CM_EHFND_FW_WFF004 - Method &1 of the basis class was not overwritten ?

  The SAP error message CM_EHFND_FW_WFF004 indicates that a method in a class that is expected to be overridden has not been implemented in a subclass. This typically occurs in the context of the SAP Business Workflow or the Enterprise Foundation (EHFND) framework, where certain methods are designed to be customized or extended in subclasses.
  Cause:
  
  Missing Implementation: The subclass that is supposed to override the method does not have an implementation for it.
  Incorrect Class Hierarchy: The subclass may not be correctly inheriting from the base class that contains the method.
  Configuration Issues: There may be configuration issues in the workflow or the application that lead to this error.
  
  Solution:
  
  
  Implement the Method: Check the subclass that is supposed to override the method and ensure that the method is implemented correctly. The method signature should match that of the base class.
  
  
  Check Class Hierarchy: Verify that the subclass is correctly defined and is indeed inheriting from the appropriate base class. You can do this by checking the class definition in the ABAP Workbench (transaction SE80 or SE24).
  
  
  Review Documentation: Consult the SAP documentation or the specific implementation guide for the framework you are working with. This may provide insights into what the method is supposed to do and how it should be implemented.
  
  
  Debugging: If you are unsure where the issue lies, you can use the ABAP debugger to trace the execution and see where the method call is failing.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on implementing the method correctly.
  
  
  Consult with Colleagues or SAP Support: If you are still unable to resolve the issue, consider reaching out to colleagues who have experience with the specific framework or contacting SAP support for assistance.
  
  
  Related Information:
  
  ABAP Class and Method Documentation: Familiarize yourself with the ABAP class and method documentation to understand the expected behavior of the methods in the base class.
  SAP Community: Engage with the SAP Community forums where other developers may have encountered similar issues and can provide insights or solutions.
  Training and Resources: If you are new to SAP development, consider taking training courses or reviewing resources related to ABAP and the specific framework you are working with.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
