  The SAP error message CNV_LTHCM_S_10251 indicates that during a conversion or migration process, the system has detected empty tables related to Human Capital Management (HCM) domains. This typically occurs in the context of data migration projects, especially when using tools like the SAP Landscape Transformation (SLT) or SAP S/4HANA Migration Cockpit.
  Cause:
  The error is triggered when the migration process identifies that certain tables, which are expected to contain data, are empty. This can happen for several reasons:
  
  Data Not Available: The source system may not have any data in the specified HCM tables.
  Incorrect Configuration: The migration settings or mappings may not be correctly configured, leading to the exclusion of data.
  Data Filtering: There may be filters applied that inadvertently exclude all records from being migrated.
  Pre-Migration Cleanup: If a cleanup process was performed before migration, it might have removed data that was expected to be migrated.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Source Data: Verify that the source system has data in the relevant HCM tables. If the tables are indeed empty, you may need to populate them with the necessary data before migration.
  
  
  Review Migration Configuration: Ensure that the migration settings are correctly configured. Check the mapping of fields and tables to ensure that data is being correctly identified for migration.
  
  
  Adjust Filters: If there are any filters applied during the migration process, review and adjust them to ensure that they are not excluding necessary data.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using (e.g., SAP S/4HANA Migration Cockpit) for guidance on handling empty tables and ensuring data integrity.
  
  
  Log Analysis: Check the migration logs for additional details about the error. This may provide insights into which specific tables are empty and why.
  
  
  Data Load Strategy: If the empty tables are expected (for example, if they are not used in the target system), you may need to adjust your data load strategy to skip these tables.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
