• What is the cause and solution for SAP error message CNVOM_DEL_TASK021 - No data deleted due to simulation ?

  The SAP error message CNVOM_DEL_TASK021 indicates that no data was deleted during a simulation run of a data deletion task. This message is part of the SAP data migration and conversion tools, particularly in the context of the SAP S/4HANA migration process or data cleansing activities.
  Cause:
  
  Simulation Mode: The error occurs because the task is being executed in simulation mode. In this mode, the system checks what would happen if the deletion were to occur, but it does not actually delete any data.
  No Data Matching Criteria: There may be no data that meets the criteria specified for deletion. This could be due to incorrect selection criteria or filters that do not match any existing records.
  Data Already Deleted: The data intended for deletion may have already been removed in a previous run or is not present in the system.
  Configuration Issues: There may be issues with the configuration of the deletion task or the parameters set for the simulation.
  
  Solution:
  
  Check Simulation Settings: Ensure that you are aware that the task is running in simulation mode. If you intend to perform actual deletions, you need to run the task in the production mode instead of simulation.
  Review Selection Criteria: Verify the selection criteria or filters used for the deletion task. Make sure they are correctly set to target the intended data.
  Data Verification: Check the database or relevant tables to confirm whether the data you expect to delete is present. If the data is not there, you may need to adjust your criteria or understand why it is missing.
  Run in Production Mode: If you are satisfied with the simulation results and want to proceed with the deletion, switch to production mode and execute the task again.
  Consult Documentation: Refer to the SAP documentation or notes related to the specific data deletion task you are working on for any additional guidance or troubleshooting steps.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SCC1 for client copy, SCC4 for client settings, or specific transaction codes related to data migration.
  SAP Notes: Check for any SAP Notes that may address known issues or provide additional context for the error message.
  Data Migration Cockpit: If you are using the Data Migration Cockpit, ensure that you are following the correct procedures for data deletion and migration.
  Testing Environment: Always perform such operations in a testing environment before executing them in production to avoid unintended data loss.
  
  If the issue persists after following these steps, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
