BUAVC014 - Details

• The SAP error message BUAVC014 indicates that an RFC (Remote Function Call) task has been restarted in serial mode. This typically occurs when there are issues with the parallel processing of tasks in the background, leading the system to revert to a serial execution mode to ensure that the tasks can still be completed.
  Causes:
  
  Resource Limitations: The system may be running low on resources (CPU, memory, etc.), causing it to switch to serial processing.
  
  Configuration Issues: The settings for parallel processing may not be configured correctly, leading to failures in executing tasks in parallel.
  Lock Contention: If multiple tasks are trying to access the same resource or data simultaneously, it can lead to lock contention, forcing the system to process tasks serially.
  Network Issues: Problems with network connectivity or performance can also lead to failures in parallel processing.
  System Load: High system load or performance issues can trigger the system to revert to serial processing
