  The SAP error message SRT_WSP3070 indicates that there has been a change in the implementation of a provider contract in the SAP system. This message typically arises in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is a mismatch between the expected and actual implementation of a web service.
  Cause:
  The error occurs when:
  
  The provider contract for a web service has been modified, which can include changes to the service interface, the implementation class, or the method signatures.
  The system is trying to invoke a web service that has been updated, but the consumer (the system or application making the call) is still referencing the old implementation.
  There may be inconsistencies in the service definitions or configurations in the Service Registry.
  
  Solution:
  To resolve the SRT_WSP3070 error, you can follow these steps:
  
  
  Check the Provider Contract: 
  
  Verify the changes made to the provider contract. Ensure that the new implementation is correctly defined and that the changes are intended.

  If the consumer application is still referencing the old implementation, update it to use the new provider contract. This may involve regenerating proxy classes or updating service references in the consumer application.
  
  
  
  Clear Cache:
  
  Sometimes, cached data can cause inconsistencies. Clear the cache in the SAP system to ensure that the latest definitions are being used.
  
  
  
  Check Service Registry:
  
  Ensure that the Service Registry is updated with the latest provider contract. If necessary, re-register the service.
  
  
  
  Test the Service:
  
  After making the necessary updates, test the web service to ensure that it is functioning correctly with the new implementation.
