• What is the cause and solution for SAP error message SR054 - aRFC terminated with error '&' ?

  The SAP error message SR054, which indicates that an "asynchronous RFC (aRFC) terminated with error '&'", typically arises in the context of asynchronous Remote Function Calls (RFC) in SAP systems. This error can occur due to various reasons, and understanding the cause is crucial for troubleshooting and resolving the issue.
  Causes of SR054 Error
  
  
  Network Issues: Problems with the network connection between the SAP systems can lead to a failure in the aRFC call.
  
  
  System Configuration: Incorrect configuration of the RFC destination or the logical system settings can cause the aRFC to fail.
  
  
  Resource Limitations: If the system is running low on resources (e.g., memory, CPU), it may not be able to process the aRFC requests.
  
  
  Transaction Errors: The function module being called via aRFC may have encountered an error during execution, leading to the termination of the call.
  
  
  Timeouts: If the aRFC call takes too long to execute, it may time out and result in an error.
  
  
  Authorization Issues: The user or system executing the aRFC may not have the necessary authorizations to perform the requested action.
  
  
  Solutions to SR054 Error
  
  
  Check Network Connectivity: Ensure that there are no network issues between the systems involved in the aRFC call. You can use tools like ping or traceroute to diagnose connectivity problems.
  
  
  Review RFC Destination Configuration: Verify the configuration of the RFC destination in transaction SM59. Ensure that the settings are correct and that the destination is reachable.
  
  
  Monitor System Resources: Use transaction SM50 or SM66 to monitor system performance and check for any resource bottlenecks. If necessary, optimize the system or increase resources.
  
  
  Analyze the Function Module: Check the function module being called for any errors or exceptions. You can use transaction SE37 to review the code and ensure it is functioning correctly.
  
  
  Increase Timeout Settings: If timeouts are suspected, consider increasing the timeout settings for the aRFC calls in the relevant configuration.
  
  
  Check Authorizations: Ensure that the user or system executing the aRFC has the necessary authorizations. You can use transaction SU53 to analyze authorization issues.
  
  
  Review Logs: Check the system logs (transaction SM21) and the aRFC logs (transaction SM58) for more detailed error messages that can provide additional context for the failure.
