• Message number: 226

• Message text: Transactional RFC: Internal error in method

What causes this issue?

The appearance of this monitoring object and attribute indicates that
the method named in the alert has had an internal problem at runtime.
The method failed to execute correctly.

How to fix this error?

Often, you must report the problem to SAP; it indicates that a
programming error has occurred.
The possible causes and your responses are as follows:
Exception: Unable to expand name. Report this problem to SAP.
Exception: Name not found. Report this problem to SAP.
Exception: Communication failure. The monitoring architecture was unable
to start the method on the server on which it is supposed to run. This
is not a programming error. You should check that all of your servers
are active, that all RFC destinations work correctly, that no network
problems exist.
Exception: Other problem. Report this problem to SAP.
Exception: Wrong segment. The method has been started (possibly by hand
in the ABAP editor) in an server other than the one in which the
monitoring architecture segment for transactional RFC is contained. Try
starting the collection tool from within Transaction RZ20. This should
correct the problem. If the message recurs, then please report the
problem to SAP.
Exception: Others. Report this problem to SAP.

• What is the cause and solution for SAP error message RT226 - Transactional RFC: Internal error in method ?

  The SAP error message RT226, which indicates a "Transactional RFC: Internal error in method," typically arises during the execution of a Transactional Remote Function Call (tRFC). This error can occur due to various reasons, including issues with the configuration, network problems, or internal inconsistencies within the SAP system.
  Causes:
  
  Configuration Issues: Incorrect settings in the tRFC configuration can lead to this error. This includes issues with the RFC destination or the logical system settings.
  Network Problems: Connectivity issues between the systems involved in the tRFC can cause failures.
  System Inconsistencies: Internal inconsistencies or corruption in the SAP system can lead to unexpected errors.
  Authorization Issues: The user executing the tRFC may not have the necessary authorizations to perform the action.
  Resource Limitations: Insufficient system resources (like memory or processing power) can lead to failures in executing tRFC calls.
  
  Solutions:
  
  
  Check Configuration:
  
  Verify the RFC destination settings in transaction SM59. Ensure that the destination is correctly configured and reachable.
  Check the logical system settings in transaction SALE to ensure they are correctly defined.
  
  
  
  Network Connectivity:
  
  Test the network connection between the systems involved. You can use tools like ping or telnet to check connectivity.
  Ensure that firewalls or network policies are not blocking the tRFC communication.
  
  
  
  Review System Logs:

  Authorization Checks:
  
  Ensure that the user executing the tRFC has the necessary authorizations. You can check this in transaction SU53 after the error occurs.
  
  
  
  Monitor System Resources:
  
  Use transaction ST02 to monitor memory usage and check for any performance bottlenecks.
  If resource limitations are identified, consider optimizing the system or increasing the resources available.
  
  
  
  Reprocessing tRFC Calls:
  
  If the error is transient, you can try to reprocess the failed tRFC calls from transaction SM58.
