• What is the cause and solution for SAP error message ML4HRUN020 - Parallel processing started ?

  The SAP error message ML4HRUN020, which indicates that "Parallel processing started," typically occurs in the context of background processing or batch jobs in SAP. This message is not necessarily an error but rather an informational message indicating that a parallel processing job has been initiated.
  Cause:
  
  Parallel Processing: The system is designed to handle multiple processes simultaneously to improve performance and efficiency. This message indicates that a job has been started in parallel mode.
  Job Configuration: The job may have been configured to run in parallel, which is common for processes that can be executed independently without dependencies.
  System Load: High system load or resource allocation may trigger parallel processing to optimize performance.
  
  Solution:
  
  Monitor Job Status: Check the status of the job in transaction codes like SM37 (Job Monitoring) to see if it is running as expected or if there are any subsequent error messages.
  Review Job Configuration: If the parallel processing is not desired, review the job configuration settings to determine if it can be modified to run in a single-threaded mode.
  Performance Tuning: If the parallel processing is causing issues (e.g., resource contention), consider tuning the system parameters or adjusting the job's parallel processing settings.
  Check Logs: Look at the application logs or job logs for any additional messages that may provide more context about the job's execution and any potential issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM37 (to monitor jobs), SM21 (to check system logs), and ST22 (to analyze dumps).
  SAP Notes: Check SAP Notes for any known issues or updates related to parallel processing and the specific job you are running.
  Documentation: Review SAP documentation regarding background processing and parallel processing to understand how it works and best practices for configuration.
