• What is the cause and solution for SAP error message CNV_10020524 - Maximum number of &2 batch processes is already running ?

  The SAP error message CNV_10020524: Maximum number of &2 batch processes is already running typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the system has reached the maximum limit of concurrent batch processes that can be executed at the same time.
  Cause:
  
  Concurrent Batch Processes: The system has a predefined limit on the number of batch processes that can run simultaneously. If this limit is reached, any new batch job will be rejected, leading to this error message.
  Long-Running Jobs: If there are long-running batch jobs that are still in progress, they can occupy the available slots for new batch processes.
  Configuration Settings: The maximum number of allowed batch processes may be set too low in the system configuration.
  
  Solution:
  
  Check Running Jobs: Use transaction codes like SM37 (Job Monitoring) to check for currently running batch jobs. Identify any jobs that may be taking longer than expected and consider terminating them if they are no longer needed.
  Increase Batch Process Limit: If necessary, you can increase the maximum number of allowed batch processes. This can typically be done in the system profile parameters. Look for parameters like rdisp/bt_max_no and adjust it according to your system's capacity and requirements.
  Schedule Jobs During Off-Peak Hours: If possible, schedule batch jobs during off-peak hours to reduce contention for resources.
  Optimize Batch Jobs: Review and optimize the batch jobs to ensure they run efficiently and do not consume unnecessary resources.
  System Performance: Ensure that the system has adequate resources (CPU, memory) to handle the expected load of batch processes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM37 for monitoring jobs, SM50 for checking active processes, and SM66 for monitoring global processes.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error.
  Documentation: Review SAP documentation related to batch processing and system configuration for best practices.
