Local fix

• Always keep the external services and the associated business
  objects in the same process application or toolkit to ensure
  that a business object can be updated when discovering or
  rediscovering external services in case the business object's
  definition changed in the WSDL file.
  
  If business objects already exist in an associated Toolkit,
  discover them directly from the toolkit.
  

Problem summary

• No additional information is available.
  

Problem conclusion

• A fix that provides a meaningful exception when a business
  object couldn't be updated during web service discovery will be
  available in a future release of Business Automation Workflow.
  

Temporary fix
