• What is the cause and solution for SAP error message NSDM_MIG_CONTROL141 - Max. number of parallel group processing jobs &1 exceeded ?

  The SAP error message NSDM_MIG_CONTROL141 indicates that the maximum number of parallel group processing jobs has been exceeded. This typically occurs in the context of data migration or data processing tasks where multiple jobs are being executed simultaneously.
  Cause:
  
  Job Limit Exceeded: The system has a predefined limit on the number of parallel jobs that can be executed for a specific task. When this limit is reached, the error is triggered.
  Configuration Settings: The maximum number of parallel jobs is often defined in the system configuration. If the workload is high or if multiple users are executing jobs simultaneously, this limit can be exceeded.
  Resource Constraints: The underlying system resources (CPU, memory, etc.) may also be a factor, as they can limit the number of jobs that can run in parallel effectively.
  
  Solution:
  
  
  Increase Parallel Job Limit:
  
  You can increase the limit for parallel jobs in the relevant configuration settings. This is usually done in transaction codes like RZ10 (for profile parameters) or through specific migration settings.
  Look for parameters related to parallel processing, such as rdisp/wp_no_dia or similar, depending on your SAP version and configuration.
  
  
  
  Monitor and Manage Jobs:
  
  Use transaction SM37 to monitor the jobs currently running. You can check if there are any jobs that can be canceled or if there are jobs that are stuck.
  If possible, stagger the execution of jobs to avoid hitting the limit.
  
  
  
  Optimize Job Execution:
  
  Review the job execution strategy. If certain jobs can be combined or if the data can be processed in smaller batches, this may help reduce the number of parallel jobs running at any one time.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to your specific version and the migration process you are using. There may be specific recommendations or best practices for managing parallel jobs.
  
  
  
  Contact SAP Support:
  
  If the issue persists or if you are unsure about making changes to the configuration, consider reaching out to SAP support for assistance.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM37 (Job Monitoring), RZ10 (Profile Parameters), and ST22 (Dump Analysis) for troubleshooting.
  SAP Notes: Check for any SAP Notes related to this error message or the specific migration process you are using. SAP Notes often contain fixes, workarounds, or additional configuration guidance.
  System Performance: Regularly monitor system performance and job execution to ensure that the system can handle the workload without hitting limits.
  
  By following these steps, you should be able to address the error and optimize your SAP environment for better job management.
