• What is the cause and solution for SAP error message CNV20200007 - Test run; no data changes are made ?

  The SAP error message CNV20200007 typically occurs during a data migration or conversion process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This message indicates that the test run of the migration process did not result in any data changes being made. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Test Run Mode: The error is expected behavior when the migration is executed in test mode. In this mode, the system simulates the migration process without making any actual changes to the database.
  No Data to Migrate: There may be no data available in the source system that meets the criteria for migration, leading to no changes being detected.
  Configuration Issues: There might be issues with the configuration settings or mapping rules that prevent any data from being processed.
  Filters Applied: If filters are applied during the migration process, they may exclude all data, resulting in no changes.
  
  Solution:
  
  Check Migration Mode: Ensure that you are aware of the mode in which you are running the migration. If you intend to make actual changes, you need to run the migration in production mode rather than test mode.
  Review Data Availability: Verify that there is data in the source system that meets the criteria for migration. You can check the source tables to ensure that data exists.
  Examine Configuration: Review the configuration settings and mapping rules in the migration cockpit to ensure they are set up correctly. Make sure that the data you expect to migrate is not being filtered out.
  Run a Full Migration: If you are satisfied with the test run results and want to proceed, run the migration in the actual mode to apply the changes.
  Logs and Documentation: Check the logs generated during the test run for any additional messages or warnings that might provide more context on why no data changes were made.
