• What is the cause and solution for SAP error message CNV_CMIS_A_20120 - Insufficient background work processes; try again later ?

  The SAP error message CNV_CMIS_A_20120 indicates that there are insufficient background work processes available to handle the requested operation. This error typically occurs during data migration or conversion processes, particularly when using the SAP Conversion Management Information System (CMIS).
  Cause:
  
  Insufficient Background Work Processes: The SAP system has a limited number of background work processes configured. If all available processes are busy or if the system is under heavy load, new requests may be queued or rejected, leading to this error.
  System Load: High system load due to other background jobs or user activities can exhaust the available work processes.
  Configuration Issues: The configuration of the SAP system may not be optimized for the workload, leading to insufficient resources for background processing.
  
  Solution:
  
  Check Background Jobs: Use transaction code SM37 to monitor and analyze the status of background jobs. Identify any long-running or stuck jobs that may be consuming resources.
  Increase Background Work Processes:
  
  Go to transaction RZ10 to adjust the profile parameters.
  Look for the parameter rdisp/wp_no_btc which defines the number of background work processes. Increase this number if necessary, based on your system's capacity and workload.
  After making changes, restart the SAP instance for the changes to take effect.
  
  
  Optimize Background Jobs: Review and optimize existing background jobs to ensure they are running efficiently. Consider scheduling jobs during off-peak hours to reduce load.
  System Performance Tuning: Analyze the overall performance of the SAP system. This may involve checking hardware resources (CPU, memory, disk I/O) and optimizing database performance.
  Retry the Operation: After addressing the above issues, retry the operation that triggered the error.
