• What is the cause and solution for SAP error message CNV_CDMC_UCIA079 - Duplicate entry already exists for the entered object type & ?

  The SAP error message CNV_CDMC_UCIA079 indicates that there is a duplicate entry for the specified object type in the system. This error typically arises during data migration or conversion processes, particularly when using the SAP Conversion Tools or during the execution of a data migration project.
  Cause:
  The error is caused by the presence of duplicate entries in the database for the object type you are trying to process. This can happen due to:
  
  Data Duplication: The source data being migrated contains duplicate records.
  Incorrect Mapping: The mapping of source data to target objects may not be correctly defined, leading to attempts to create duplicate entries.
  Previous Migration Attempts: If a migration process was partially completed or failed, it might have left behind some entries that are now causing conflicts.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Check the source data for duplicates. You can use tools like Excel or SQL queries to identify duplicate records based on the key fields of the object type.
  If duplicates are found, decide how to handle them (e.g., remove, merge, or update).
  
  
  
  Review Mapping:
  
  Ensure that the mapping of the source data to the target object type is correct. Verify that the keys used for the migration are unique and correctly defined.
  
  
  
  Clean Up Existing Data:
  
  If the target system already has entries that conflict with the new data, you may need to clean up the existing data. This could involve deleting or updating records in the target system.
  
  
  
  Re-run Migration:
  
  After resolving the duplicates and ensuring the mapping is correct, re-run the migration process.
  
  
  
  Check Logs:
  
  Review the logs generated during the migration process for additional details on the error. This can provide insights into which specific entries are causing the conflict.
