• What is the cause and solution for SAP error message /AIF/RFC_APP002 - Message &1 could not be restarted; a scheduler conflict occurred ?

  The SAP error message /AIF/RFC_APP002 Message &1 could not be restarted; a scheduler conflict occurred typically indicates that there is a conflict in the scheduling of asynchronous messages in the Application Interface Framework (AIF). This can happen when multiple processes are trying to access or process the same message simultaneously, leading to a situation where the message cannot be restarted.
  Causes:
  
  Concurrent Processing: Multiple instances of the same message are being processed at the same time, leading to a conflict.
  Locking Issues: The message might be locked by another process, preventing it from being restarted.
  Configuration Issues: Incorrect configuration in the AIF settings or in the RFC destination settings can lead to scheduling conflicts.
  System Performance: High system load or performance issues can cause delays in processing, leading to conflicts.
  
  Solutions:
  
  Check Message Status: Review the status of the message in the AIF monitor. If it is in a "processing" state, wait for it to complete before attempting to restart.
  Review Logs: Check the application logs for any additional error messages or warnings that might provide more context about the conflict.
  Adjust Scheduling: If you have control over the scheduling of the processes, consider adjusting the frequency or timing to avoid conflicts.
  Increase System Resources: If the issue is related to system performance, consider increasing the resources available to the SAP system (e.g., CPU, memory).
  Configuration Review: Review the AIF configuration settings to ensure that they are set up correctly and that there are no conflicts in the RFC destinations.
  Manual Intervention: If necessary, manually intervene by stopping the conflicting process or releasing locks on the message.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SLG1 (Application Log) to check logs for more details on the error.
  AIF Monitoring: Use transaction /AIF/IFMON to monitor the status of messages and identify any that are in conflict.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide patches related to AIF and RFC processing.
  Documentation: Refer to the official SAP documentation for AIF for best practices and configuration guidelines.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or AIF support team for further investigation.
