  The SAP error message CNV20600188 indicates that during a test run of a data migration or conversion process, the system found that the tables SCMG_T_CASE_ATTR and UDMCASEATTR00 were not modified. This typically occurs in the context of a data migration project, often related to the SAP S/4HANA conversion or similar projects.
  Cause:
  
  No Data Changes: The most common cause of this error is that there were no changes made to the data in the specified tables during the test run. This could be due to the absence of relevant data or the conditions set for the migration not being met.
  Configuration Issues: There may be configuration settings that prevent the tables from being modified during the test run.
  Test Run Mode: The test run mode is designed to simulate the migration process without making actual changes. If the conditions for modification are not met, the tables will remain unchanged.

  Solution:
  
  Check Data: Verify that there is data in the source tables that should be migrated to the target tables. If there is no data, the tables will not be modified.
  Review Migration Settings: Check the configuration settings for the migration process to ensure that they are correctly set up to allow modifications.
  Run in Actual Mode: If you are confident that the migration should result in changes, consider running the migration in actual mode instead of test mode. However, ensure that you have backups and a rollback plan in place.
  Analyze Logs: Review the logs generated during the test run for any additional error messages or warnings that could provide more context on why the tables were not modified.
  Consult Documentation: Refer to the SAP documentation related to the specific migration or conversion process you are executing. There may be specific prerequisites or steps that need to be followed.
