This error indicates that the system has disabled parallel processing for a specific operation, which can lead to performance issues or delays in processing.
  Cause:
  
  Configuration Issues: The parallel processing settings in the SAP TM configuration may not be set correctly.

  Locks or Deadlocks: There may be locks on the database or deadlocks that prevent parallel processing from being executed.
  Custom Code or Enhancements: Custom developments or enhancements may interfere with the standard processing logic, leading to this error.
