  The SAP error message SRT_WSP3200 indicates that there was a failure in deserializing a response for a web service call. This typically occurs when the data received from the web service does not match the expected format or structure defined in the SAP system. The error message provides placeholders for specific details:
  
  &1: The type of the data that failed to deserialize.

  Causes
  
  
  Mismatch in Data Structure: The data structure returned by the web service does not match the expected structure defined in the SAP system. This can happen if the web service has been updated or if there are discrepancies in the WSDL (Web Services Description Language) file.
  
  
  Versioning Issues: If the web service has multiple versions, the SAP system might be calling an outdated version that does not conform to the expected data format.
  
  
  Data Type Issues: The data types in the response may not match the expected types in the SAP system, leading to deserialization failures.
  
  
  Network Issues: Sometimes, network issues can lead to incomplete or corrupted data being received, which can also cause deserialization errors.
  
  
  Configuration Issues: Incorrect configuration of the web service consumer in SAP can lead to deserialization problems.
  
  
  Solutions
  
  
  Check WSDL and Data Structure: Verify the WSDL file of the web service and ensure that the data structure matches what is expected in the SAP system. If there have been changes to the web service, update the WSDL in SAP.
  
  
  Update Service Definitions: If the web service has been updated, regenerate the service definitions in SAP to ensure that they are in sync with the latest version of the web service.

  Check Network Connectivity: Ensure that there are no network issues affecting the communication between SAP and the web service.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address known issues related to web service deserialization.
  
  
  Debugging: If you have access to the SAP system, consider enabling debugging for the web service call to get more detailed logs that can help identify the root cause of the issue.
