• What is the cause and solution for SAP error message SHTTP000 - Handler class &1 does not implement interface IF_HTTP_EXTENSION ?

  The SAP error message SHTTP000 indicates that a handler class specified in your HTTP service does not implement the required interface IF_HTTP_EXTENSION. This typically occurs when you are trying to use a custom HTTP handler in an SAP system, and the class you have defined does not conform to the expected interface.
  Cause:
  
  Missing Interface Implementation: The handler class you are using does not implement the IF_HTTP_EXTENSION interface, which is necessary for it to function as an HTTP handler.
  Incorrect Class Name: The class name specified in the HTTP service configuration might be incorrect or misspelled.
  Class Not Activated: The class may not be activated in the ABAP Workbench, which can lead to this error.
  Namespace Issues: If the class is in a different namespace, it may not be accessible as expected.
  
  Solution:
  
  
  Implement the Interface: Ensure that your handler class implements the IF_HTTP_EXTENSION interface. You can do this by modifying the class definition in the ABAP Workbench (SE80 or SE24). The class should look something like this:
  CLASS your_handler_class DEFINITION
    INHERITING FROM cl_http_extension
    FINAL
    CREATE PUBLIC.
  
  PUBLIC SECTION.
    INTERFACES if_http_extension.
  ENDCLASS.
  
  
  Check Class Name: Verify that the class name specified in the HTTP service configuration is correct. You can check this in transaction SE80 or SE24.
  
  
  Activate the Class: If the class is not activated, activate it in the ABAP Workbench. You can do this by navigating to the class in SE80 or SE24 and clicking on the "Activate" button.
  
  
  Check Namespace: Ensure that the class is in the correct namespace and is accessible from the context in which it is being called.
  
  
  Debugging: If the issue persists, you can use transaction SLG1 to check for any logs related to the HTTP service and see if there are additional error messages that can provide more context.
  
  
  Related Information:
