  The SAP error message CNV_OM_PRESEL141: None of the selected tasks is ready, thus nothing happens typically occurs in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the tasks you have selected for processing are not in a state that allows them to be executed.
  Causes:
  
  Task Status: The selected tasks may not be in a "ready" state. This could be due to previous tasks not being completed, or they may be in a status that prevents them from being executed (e.g., "in progress," "failed," or "not started").
  Dependencies: There may be dependencies between tasks that have not been resolved. For example, a prerequisite task must be completed before the selected task can be executed.
  Configuration Issues: There may be configuration issues in the migration cockpit or the data migration process that prevent the tasks from being recognized as ready.
  Data Issues: The data being processed may have issues that prevent the tasks from being executed, such as missing required fields or invalid data formats.
  
  Solutions:
  
  Check Task Status: Review the status of the selected tasks in the migration cockpit. Ensure that all prerequisite tasks are completed and that the tasks you are trying to execute are marked as "ready."
  Resolve Dependencies: If there are dependencies, complete the prerequisite tasks first. Make sure that all necessary steps in the migration process are followed.
  Review Configuration: Check the configuration settings in the migration cockpit to ensure that everything is set up correctly. This includes verifying that the correct source and target systems are configured.
  Data Validation: Validate the data being processed to ensure that it meets all requirements. Look for any errors or warnings in the data that may need to be addressed.
  Logs and Traces: Check the logs and traces for more detailed error messages that can provide insight into why the tasks are not ready. This can help identify specific issues that need to be resolved.
