• What is the cause and solution for SAP error message /AIF/MES128 - Raw data structure was not determined ?

  The SAP error message /AIF/MES128 Raw data structure was not determined typically occurs in the context of the Application Interface Framework (AIF) when the system is unable to determine the appropriate raw data structure for processing incoming messages. This can happen for various reasons, including configuration issues, missing mappings, or incorrect message types.
  Causes:
  
  Missing Configuration: The raw data structure may not be configured correctly in the AIF settings.
  Incorrect Message Type: The message type being processed may not have a corresponding raw data structure defined.
  Mapping Issues: There may be issues with the mapping between the incoming message and the expected raw data structure.
  Inconsistent Data: The incoming data may not conform to the expected format, leading to the inability to determine the raw data structure.
  Transport Issues: If the message is being transported from one system to another, there may be discrepancies in the configuration between the systems.
  
  Solutions:
  
  
  Check Configuration:
  
  Go to the AIF configuration settings and ensure that the raw data structure is defined for the message type you are processing.
  Verify that the relevant mappings are correctly set up.
  
  
  
  Review Message Type:
  
  Ensure that the message type being sent matches the expected message type in the AIF configuration.
  Check if the message type is active and properly defined.
  
  
  
  Validate Incoming Data:
  
  Inspect the incoming data for any inconsistencies or formatting issues that may prevent the system from recognizing the raw data structure.
  Use transaction codes like /AIF/MSG to analyze the messages and identify any errors.
  
  
  
  Check Mapping:
  
  Review the mapping configuration to ensure that it correctly maps the incoming message to the expected raw data structure.
  If necessary, create or adjust the mapping to align with the incoming data format.
  
  
  
  Transport Configuration:
  
  If the issue arises in a transport scenario, ensure that the AIF configuration is consistent across the source and target systems.
  Check for any missing transport requests that may contain necessary configuration changes.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the AIF processing to identify where the determination of the raw data structure fails.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /AIF/MSG for message monitoring and /AIF/CONFIG for configuration settings.
  SAP Notes: Check SAP Notes for any known issues or patches related to AIF and the specific error message.
  Documentation: Refer to the official SAP documentation for AIF for detailed guidance on configuration and troubleshooting.
  
  By following these steps, you should be able to identify the root cause of the error and implement the necessary solutions to resolve it.
