  The SAP error message CNV_LTHCM_S_10241 indicates that during a data migration or conversion process, the system has detected tables that were previously non-existing but are now defined in the system. This typically occurs in the context of the SAP Landscape Transformation (SLT) or during data migration projects, particularly when using tools like the SAP Data Migration Cockpit or SAP S/4HANA Migration Cockpit.
  Cause:
  
  Schema Changes: The error can arise if there have been changes in the database schema, such as the addition of new tables or modifications to existing tables that were not accounted for in the migration process.

  Solution:
  
  Review Migration Configuration: Check the migration configuration settings to ensure that they are up-to-date and reflect the current database schema. Make adjustments as necessary.
  Update Mapping: If new tables have been added, ensure that they are included in the mapping and transformation rules of the migration process.
  Check for Dependencies: Investigate if the newly defined tables have dependencies on other tables or data that need to be addressed before proceeding with the migration.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand how to handle newly defined tables and any related configurations.
  Testing: Conduct thorough testing in a development or sandbox environment to ensure that the migration process works as expected with the updated schema before executing it in production.
