Smart SAP Assistant

• What is the cause and solution for SAP error message /AIF/XRFC_MESSAGES035 - Kernel error during serialization of RFC parameters. ?

  The SAP error message /AIF/XRFC_MESSAGES035 Kernel error during serialization of RFC parameters typically indicates an issue with the serialization of Remote Function Call (RFC) parameters in the Application Interface Framework (AIF). This error can occur due to various reasons, including data type mismatches, incorrect parameter configurations, or issues with the underlying kernel.
  Causes:
  
  Data Type Mismatch: The parameters being passed in the RFC call may not match the expected data types defined in the function module.
  Large Data Volume: If the data being serialized is too large, it may exceed the limits set by the system.
  Kernel Issues: There may be a problem with the SAP kernel version being used, which could lead to serialization errors.
  Configuration Issues: Incorrect configuration in the AIF or RFC destination settings can lead to serialization problems.
  Network Issues: Network interruptions or issues can also cause serialization errors during the transmission of data.
  
  Solutions:
  
  Check Data Types: Verify that the data types of the parameters being passed in the RFC call match the expected types in the function module. Ensure that the structure and length of the data are correct.
  Reduce Data Volume: If possible, try to reduce the size of the data being sent in the RFC call. This can be done by splitting the data into smaller chunks or optimizing the data being sent.
  Update Kernel: Ensure that you are using a supported and up-to-date version of the SAP kernel. If necessary, apply the latest patches or updates.
  Review AIF Configuration: Check the configuration settings in the AIF to ensure that they are set up correctly. This includes reviewing the RFC destination settings and ensuring that they are properly configured.
  Check Network Stability: Ensure that there are no network issues that could be causing interruptions during the RFC call. This may involve checking network logs or consulting with your network team.
  Debugging: If the issue persists, consider enabling debugging for the AIF or the RFC call to gather more detailed information about the error. This can help identify the specific parameter or data causing the issue.
