How to fix this error?

For more hints on possible causes of the error, see the Online Help in
R3up. Use transaction SE37 to test the function module. If you are
prompted for the parameters in the test environment, the problem is most
likely not in the SAP system. In this case, restart SAPup from the
beginning.
If the function module raises a specific exception, there must be a
problem with this function module, not with RFC. If you cannot find any
information on this error in the Online Help for the upgrade, contact
SAP Support.

• What is the cause and solution for SAP error message TQ235 - Function module call & using RFC canceled (error status &) ?

  The SAP error message TQ235, which indicates that a function module call using Remote Function Call (RFC) was canceled, can arise from various issues. Here’s a breakdown of potential causes, solutions, and related information:
  Causes:
  
  Network Issues: Problems with the network connection between the SAP systems can lead to RFC calls being canceled.
  Timeouts: If the function module takes too long to execute, it may exceed the timeout settings, resulting in a cancellation.
  System Load: High load on the SAP system can cause delays in processing, leading to canceled calls.
  Authorization Issues: The user executing the RFC may not have the necessary authorizations to perform the function.
  Configuration Errors: Incorrect settings in the RFC destination or the function module itself can lead to failures.
  Function Module Errors: The function module being called may have its own internal errors or exceptions that cause it to fail.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues between the systems involved in the RFC call.
  Increase Timeout Settings: If timeouts are an issue, consider increasing the timeout settings for the RFC connection.
  Monitor System Performance: Check the performance of the SAP system to ensure it is not overloaded. You may need to optimize performance or schedule jobs during off-peak hours.
  Review Authorizations: Verify that the user has the necessary authorizations to execute the function module.
  Check RFC Destination Configuration: Ensure that the RFC destination is correctly configured and that the connection parameters are accurate.
  Debug the Function Module: If the function module is failing, debug it to identify any internal errors or exceptions that may be causing the cancellation.
  Review Logs: Check the system logs (transaction SM21) and the RFC trace (transaction SM58) for more detailed error messages that can provide insights into the issue.
