• What is the cause and solution for SAP error message SRT_WSP766 - Fallback logical port not possible due to allocation to XI protocol ?

  The SAP error message SRT_WSP766 indicates that there is an issue with the configuration of a logical port in the context of web service communication. Specifically, this error occurs when a fallback logical port cannot be used because it is allocated to the XI (Exchange Infrastructure) protocol.
  Cause:
  
  Logical Port Configuration: The logical port you are trying to use is configured to use the XI protocol, which does not support fallback mechanisms. Fallback is typically used for web service communication when the primary endpoint is unavailable.
  Service Configuration: The service you are trying to call may not have a proper fallback configuration set up, or the logical port is not correctly defined for the intended communication method.
  Protocol Mismatch: The system is expecting a different protocol for the communication than what is currently configured.
  
  Solution:
  
  
  Check Logical Port Configuration:
  
  Go to the transaction SOAMANAGER in your SAP system.
  Navigate to the Web Service Configuration section.
  Locate the logical port that is causing the issue and check its configuration.
  Ensure that the logical port is not set to use the XI protocol if you intend to use fallback.
  
  
  
  Modify Logical Port:
  
  If the logical port is indeed set to use the XI protocol, consider creating a new logical port that uses a different protocol (e.g., HTTP or HTTPS) that supports fallback.
  Ensure that the new logical port is correctly configured with the necessary endpoint and authentication details.
  
  
  
  Fallback Configuration:
  
  If you need to use fallback, ensure that the fallback logical port is properly defined and that it points to a valid service endpoint.
  Check the fallback settings in the service definition to ensure they are correctly set up.
  
  
  
  Testing:
  
  After making changes, test the web service call again to ensure that the error is resolved.
