  The SAP error message SRT_WSP3073 indicates that there has been a change in the implementation of a consumer contract in the context of SAP's web services. This message typically arises in scenarios where a web service consumer is trying to access a service that has undergone changes in its contract (WSDL) or implementation.
  Cause:
  
  Change in Service Definition: The service definition (WSDL) has been modified, which may include changes in the operations, input/output parameters, or data types.
  Versioning Issues: The consumer might be using an outdated version of the service that does not match the current implementation.
  Configuration Changes: Changes in the configuration of the service or the consumer settings in SAP can lead to this error.
  
  Solution:
  
  Update the Consumer: Ensure that the consumer application is updated to use the latest version of the service. This may involve regenerating the proxy or updating the service reference in the consumer application.
  Check Service Implementation: Review the changes made to the service implementation. If the changes are not compatible with the existing consumer, you may need to adjust the consumer code accordingly.
  Version Management: If the service has multiple versions, ensure that the correct version is being called by the consumer. You may need to specify the version explicitly in the consumer configuration.
  Testing: After making the necessary updates, perform thorough testing to ensure that the consumer can successfully interact with the updated service.
  
  Related Information:
  
  SAP Documentation: Refer to SAP's official documentation for web services and service-oriented architecture (SOA) for detailed guidance on managing service contracts and consumer implementations.
