• What is the cause and solution for SAP error message SRT_WSP894 - No Logical Port for this Secure Token Service URL: "&1" ?

  The SAP error message SRT_WSP894 indicates that there is no logical port configured for the specified Secure Token Service (STS) URL. This error typically occurs in scenarios where SAP systems are trying to communicate with a web service that requires a secure token for authentication, but the necessary configuration is missing.
  Cause:
  
  Missing Logical Port: The logical port that should be associated with the STS URL is not defined in the SAP system.
  Incorrect Configuration: The logical port may be incorrectly configured or not activated.
  Service URL Issues: The STS URL provided may be incorrect or not reachable.
  Transport Layer Security (TLS) Issues: If the STS requires a secure connection, there may be issues with the TLS configuration.
  
  Solution:
  To resolve the error, follow these steps:
  
  
  Check Logical Port Configuration:
  
  Go to transaction SOAMANAGER in your SAP system.
  Navigate to the Service Configuration section.
  Look for the logical port that corresponds to the STS URL mentioned in the error message.
  If it does not exist, create a new logical port.
  
  
  
  Create/Modify Logical Port:
  
  In SOAMANAGER, select the relevant web service and click on Create Logical Port.
  Fill in the required details, including the STS URL, and ensure that the authentication method is set correctly (e.g., Basic Authentication, WS-Security).
  Save the configuration.
  
  
  
  Test the Configuration:
  
  After creating or modifying the logical port, test the connection to ensure that it can successfully reach the STS URL.
  You can use the Test button in SOAMANAGER to verify the connection.
  
  
  
  Check for Network Issues:
  
  Ensure that there are no network issues preventing access to the STS URL.
  Check firewall settings, proxy configurations, and ensure that the URL is reachable from the SAP system.
  
  
  
  Review Security Settings:
  
  If the STS requires specific security settings (like certificates), ensure that these are correctly configured in the SAP system.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific web service you are trying to connect to for any additional configuration steps that may be required.
