• What is the cause and solution for SAP error message CNV043 - Different duplicate processing types set for table &1 ?

  The SAP error message CNV043 indicates that there are different duplicate processing types set for a specific table in the context of a data migration or conversion process. This error typically arises during the execution of a data migration project, particularly when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit.
  Cause:
  The error occurs when the system detects that the same table has been configured with different settings for handling duplicates. This inconsistency can happen due to:
  
  Configuration Issues: Different parts of the migration process may have been configured to handle duplicates in various ways (e.g., some parts may be set to ignore duplicates while others may be set to reject them).
  Multiple Migration Objects: If multiple migration objects are defined for the same table with conflicting duplicate handling settings.
  Inconsistent Data: The data being migrated may have inconsistencies that lead to different interpretations of how duplicates should be processed.
  
  Solution:
  To resolve the CNV043 error, you can follow these steps:
  
  
  Check Configuration: Review the configuration settings for the migration project. Ensure that all settings related to duplicate processing for the specific table are consistent across all migration objects.
  
  
  Standardize Duplicate Handling: Decide on a uniform approach for handling duplicates (e.g., whether to ignore, reject, or merge duplicates) and apply this setting consistently across all relevant migration objects.
  
  
  Review Migration Objects: If you have multiple migration objects for the same table, ensure that they are not conflicting in terms of duplicate processing settings.
  
  
  Data Cleansing: If the data itself is causing the issue, consider performing data cleansing to remove or standardize duplicates before the migration process.
  
  
  Consult Documentation: Refer to the SAP documentation or guides related to the specific migration tool you are using for any additional configuration steps or best practices.
  
  
  Testing: After making the necessary adjustments, run a test migration to ensure that the error is resolved and that the data is processed as expected.
