• What is the cause and solution for SAP error message DAAG_COMMON008 - Runtime class &1 does not implement interface &2 ?

  The SAP error message DAAG_COMMON008 indicates that there is a runtime issue where a class does not implement a specified interface. This typically occurs in ABAP programming when an object of a class is expected to implement certain methods defined in an interface, but it does not.
  Cause:
  
  
  Class Implementation: The class that is being instantiated or called does not implement the required interface. This can happen if:
  
  The class was not designed to implement the interface.
  The interface was changed or updated, and the class was not modified accordingly.
  There is a typo or mismatch in the class or interface name.
  
  
  
  Incorrect Object Type: The object being used may not be of the expected type, leading to a mismatch between the class and the interface.
  
  
  Versioning Issues: If there are multiple versions of the class or interface, the system might be referencing an outdated version that does not implement the required methods.
  
  
  Solution:
  
  
  Check Class Implementation:
  
  Verify that the class specified in the error message implements the interface mentioned. You can do this by checking the class definition in the ABAP Workbench (SE80 or SE24).
  If the class does not implement the interface, you may need to modify the class to implement the required methods.
  
  
  
  Update Class:
  
  If the interface has been updated, ensure that the class is updated to implement any new methods or changes in the interface.
  
  
  
  Check Object Type:
  
  Ensure that the object being instantiated is of the correct class type that implements the required interface.
  
  
  
  Recompile:
  
  Sometimes recompiling the class or interface can resolve issues related to outdated references.
  
  
  
  Debugging:
  
  Use the ABAP debugger to trace where the error occurs. This can help identify the specific line of code that is causing the issue.
  
  
  
  Consult Documentation:
  
  Review the documentation for the interface and class to ensure that you are using them correctly.
