This error typically arises in scenarios where SAP systems are integrated with other systems or applications that require SSO capabilities, such as when using web services or when integrating with cloud services.
  Cause
  The primary causes of this error include:
  
  Missing STS Configuration: The STS is not properly configured in the SAP system to handle SSO authentication requests.
  Incorrect Endpoint: The endpoint for the STS may not be correctly set up or may be pointing to an incorrect or non-existent service.
  Authentication Method: The authentication method configured in the SAP system may not support SSO, or the necessary certificates or keys may not be in place.
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the STS.
  
  Solution
  To resolve the SRT_WSP836 error, you can follow these steps:
  
  
  Check STS Configuration:
  
  Go to the SAP NetWeaver Administrator (NWA) or the relevant configuration area in your SAP system.
  Ensure that the STS is configured correctly for SSO. This includes checking the service endpoint, authentication methods, and any required certificates.
  
  
  
  Configure SSO:
  
  If SSO is not configured, you will need to set it up. This typically involves:
  
  Configuring the Identity Provider (IdP) settings.

  You can test the endpoint using tools like Postman or a web browser to ensure it is reachable.
  
  
  
  Check Network Connectivity:
  
  Ensure that there are no firewall or network issues preventing access to the STS.
  Verify that the SAP system can communicate with the STS endpoint.
  
  
  
  Review Logs:
  
  Check the SAP system logs for any additional error messages or warnings that may provide more context about the issue.
  Look for logs related to security, authentication, and web service calls.
