• What is the cause and solution for SAP error message OO071 - Interface & does not include any further interfaces ?

  The SAP error message OO071 typically indicates that there is an issue with the interface definition in the ABAP Objects (Object-Oriented Programming) context. Specifically, the message states that the interface you are trying to use does not include any further interfaces, which can lead to problems when trying to implement or use the interface in question.
  Cause:
  
  Empty Interface Definition: The interface you are trying to implement or use does not have any methods or attributes defined. This can happen if the interface was created but not properly defined.
  Incorrect Interface Hierarchy: The interface may be expected to inherit from another interface, but it does not, leading to a situation where it is not usable as intended.
  Implementation Issues: If you are trying to implement an interface in a class, and the interface does not have any methods, the implementation may not be valid.
  
  Solution:
  
  Check Interface Definition: Go to the interface definition in the ABAP Workbench (transaction SE80 or SE11) and ensure that it has methods or attributes defined. If it is empty, you will need to add the necessary methods or attributes.
  Review Inheritance: If the interface is supposed to inherit from another interface, ensure that the inheritance is correctly defined. You can do this by checking the interface's properties in the ABAP Workbench.
  Implementing Classes: If you are implementing the interface in a class, ensure that the class implements all the methods defined in the interface. If the interface is empty, you may need to reconsider the design.
  Recreate the Interface: If the interface is not being used correctly and is empty, consider recreating it with the necessary methods and attributes.
  
  Related Information:
  
  Transaction Codes: Use SE80 (Object Navigator) or SE11 (Data Dictionary) to navigate to the interface and check its definition.
  Documentation: Review the SAP documentation on ABAP Objects and interfaces to understand how to properly define and implement interfaces.
  Debugging: If you are encountering this error during runtime, consider using the ABAP debugger to trace where the error occurs and gather more context about the issue.
  
  By following these steps, you should be able to resolve the OO071 error and ensure that your interface is correctly defined and usable in your ABAP programs.
