• What is the cause and solution for SAP error message CNV_00001208 - Duplicate handling was set to 'Ignore duplicate entries' for table &1 ?

  The SAP error message CNV_00001208 indicates that during a data migration or conversion process, the system encountered duplicate entries in a specific table (denoted as &1 in the message). The handling setting for duplicates was configured to "Ignore duplicate entries," which means that the system is set to skip any duplicate records it encounters instead of processing them.
  Cause:
  
  Duplicate Data: The primary cause of this error is the presence of duplicate records in the source data that is being migrated or converted into the SAP system.
  Configuration Settings: The data migration tool or program has been configured to ignore duplicates, which can lead to this message being triggered when duplicates are detected.
  
  Solution:
  
  Review Source Data: Check the source data for duplicates. You can use data analysis tools or SQL queries to identify and resolve duplicate entries before the migration process.
  Change Duplicate Handling Settings: If you want to process duplicates instead of ignoring them, you can change the duplicate handling setting in the migration tool. However, be cautious with this approach, as it may lead to data integrity issues if not managed properly.
  Data Cleansing: Implement data cleansing processes to remove or consolidate duplicate records in the source data before migration.
  Consult Documentation: Refer to the specific documentation for the migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) for detailed instructions on handling duplicates.
  
  Related Information:
  
  Migration Tools: Familiarize yourself with the specific migration tools and their settings, as they may have different options for handling duplicates.
  Data Quality: Ensure that data quality checks are in place before migration to minimize issues related to duplicates.
  Testing: Conduct thorough testing of the migration process in a non-production environment to identify and resolve any issues related to duplicate entries before executing the migration in the live system.
  
  By addressing the root cause of the duplicates and adjusting the handling settings as necessary, you can resolve the CNV_00001208 error and ensure a smoother data migration process.
