• What is the cause and solution for SAP error message SHTTP009 - Service & has no handler class or no existing one. ?

  The SAP error message SHTTP009 indicates that a service in the SAP system does not have an associated handler class or that the handler class does not exist. This error typically occurs in the context of SAP Web Application Server (WAS) or when dealing with SAP Gateway services.
  Cause:
  
  Missing Handler Class: The service you are trying to access does not have a handler class defined in the system.
  Incorrect Configuration: The service might be incorrectly configured, leading to the system being unable to find the appropriate handler.
  Transport Issues: If the service was recently transported from one system to another, the handler class may not have been included in the transport.

  Ensure that the service is active and properly configured.

  If it does not exist, you may need to create it or transport it from another system.
  
  
  
  Check Service Implementation:
  
  Ensure that the service implementation is correctly defined and that the handler class is linked to the service.
