  Causes of SAI_MAPPING305
  
  
  Missing or Incorrect Interface Mapping: The interface mapping for the sender and receiver might not be correctly defined or might be missing altogether.
  
  
  Incorrect Configuration: The configuration settings for the interface determination might be incorrect, such as the wrong message type or service interface being specified.
  
  
  Data Type Issues: The data being sent might not match the expected data types defined in the interface mapping, leading to evaluation failures.
  
  
  Version Mismatch: There could be a version mismatch between the sender and receiver interfaces, causing the system to fail in determining the correct interface.
  
  
  Transport Issues: If the relevant objects (like mappings or interfaces) have not been transported correctly to the target system, it can lead to this error.
  
  
  Solutions to SAI_MAPPING305
  
  
  Check Interface Mapping: Verify that the interface mapping is correctly defined in the Integration Directory. Ensure that the sender and receiver interfaces are correctly specified.
