• What is the cause and solution for SAP error message SRT_WSP063 - Specified subjects have different types ?

  The SAP error message SRT_WSP063 indicates that there is a type mismatch between the subjects (or parameters) being used in a web service call. This typically occurs in scenarios involving SAP Process Integration (PI) or SAP Process Orchestration (PO) when the data types defined in the service interface do not match the data types being sent or received.
  Cause:
  
  Mismatched Data Types: The most common cause is that the data types of the input or output parameters in the web service interface do not match the expected types defined in the WSDL (Web Services Description Language) or the service interface.
  Incorrect Mapping: If you are using a mapping tool (like graphical mapping or XSLT), the mapping might not be correctly configured, leading to type mismatches.
  Changes in Service Definition: If the service definition has been changed (e.g., new fields added, types modified) but the consumer of the service has not been updated accordingly, this can lead to mismatches.
  Versioning Issues: If different versions of the service are being used, it may lead to inconsistencies in the expected data types.
  
  Solution:
  
  Check WSDL and Service Interface: Verify the WSDL and the service interface definitions to ensure that the data types of the parameters match what is being sent or received.
  Update Mappings: If you are using mappings, ensure that they are correctly configured to handle the data types as expected. You may need to adjust the mapping logic to convert or handle the data types appropriately.
  Regenerate Proxy Classes: If you are using proxy classes in your application, regenerate them to ensure they are in sync with the latest service definition.
  Test with Sample Data: Use sample data that matches the expected types to test the service call. This can help identify if the issue is with the data being sent.
  Check for Changes: If there have been recent changes to the service interface, ensure that all consumers of the service are updated to reflect those changes.
  Consult Documentation: Review any relevant documentation or release notes for the service to understand any changes that may have affected the data types.
