• What is the cause and solution for SAP error message CNV_CDMC_CA058 - Currently no resources available to initialize parallel processing ?

  The SAP error message CNV_CDMC_CA058 indicates that there are currently no resources available to initialize parallel processing in the context of a data conversion or migration process. This error typically arises in scenarios where the system is attempting to execute tasks in parallel but cannot allocate the necessary resources (such as background processing jobs or system capacity) to do so.
  Causes:
  
  Insufficient Background Processing Capacity: The system may not have enough background processing jobs available to handle the parallel tasks.
  System Resource Limitations: The server may be under heavy load, leading to a lack of available resources (CPU, memory, etc.) for parallel processing.
  Configuration Issues: There may be configuration settings that limit the number of parallel processes that can be executed.
  Locks or Long-Running Processes: Other processes may be holding locks or consuming resources, preventing new parallel processes from being initialized.
  
  Solutions:
  
  
  Check Background Job Configuration:
  
  Go to transaction SM37 to check the status of background jobs. Ensure that there are no long-running jobs that are consuming resources.
  Review the configuration in transaction SM36 to ensure that the number of parallel jobs is set appropriately.
  
  
  
  Increase Background Processing Capacity:
  
  If the system is under heavy load, consider increasing the number of background work processes in the system profile. This can be done by adjusting the parameters in the instance profile (e.g., rdisp/wp_no_btc).
  
  
  
  Monitor System Performance:
  
  Use transaction ST03N or ST06 to monitor system performance and identify any bottlenecks. Look for high CPU or memory usage that may be affecting resource availability.
  
  
  
  Check for Locks:
  
  Use transaction SM12 to check for any locks that may be preventing processes from starting. If there are unnecessary locks, they can be released.
  
  
  
  Review Parallel Processing Settings:
  
  Check the settings for parallel processing in the specific data migration or conversion tool you are using. Ensure that the settings allow for the desired level of parallelism.
  
  
  
  Restart the Process:
  
  Sometimes, simply restarting the data migration or conversion process can resolve temporary resource allocation issues.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Review the documentation for the specific data migration or conversion tool you are using, as it may have specific recommendations for handling parallel processing issues.
  System Logs: Check the system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the resource availability issue.
