SPRX042 - Details

• The SAP error message SPRX042 indicates that there is an issue with the Web Service Definition Language (WSDL) file generated for a proxy object. Specifically, the error message "interface without methods" suggests that the interface defined in the WSDL does not contain any methods, which is a requirement for a valid proxy interface.
  Causes:
  
  Empty Interface: The most common cause is that the interface you are trying to expose as a web service does not have any methods defined. This can happen if the interface was created but no methods were added to it.
  Incorrect Configuration: There may be a misconfiguration in the service definition or the proxy generation settings.
  Missing Implementation: If the interface is supposed to have methods but they are not implemented or not properly defined, this can lead to the error.
  Transport Issues: Sometimes, issues with the transport layer or the way the service is being called can lead to this
