Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Service Configuration: The service in question may not be configured to support soft state mode. Soft state mode is a feature that allows the service to maintain state information across multiple requests.
  Service Implementation: The implementation of the service might not be designed to handle soft state requests, which can lead to this error.

  Gateway Version: There may be compatibility issues with the version of the SAP Gateway being used.
  
  Solution:
  
  
  Check Service Configuration:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW) and check the service configuration.
  Ensure that the service is set up to support soft state mode if that is required for your application.
  
  
  
  Modify Service Implementation:
  
  If you have access to the service implementation, review the code to ensure it can handle soft state requests. This may involve modifying the logic to maintain state information.
  
  
  
  Adjust Request Type:
  
  Review the request being sent to the service. Ensure that it matches the expected request type and parameters defined in the service.
  
  
  
  Check Gateway Version:

  Consult Documentation:
  
  Review the SAP documentation for the specific service and the error message to understand any additional requirements or configurations that may be necessary.
  
  
  
  Contact SAP Support:
