If you run batch de-duplication as part of the Import Batch to TCA Registry program, you can run the Import Batch De-Duplication report:
After the preimport processes and before the actual import, to preview the de-duplication results.
After the import, to view the actual de-duplication results.
The report shows the duplicates that were identified and resolved within the batch that you are importing from the interface tables. This de-duplication does not resolve duplicates between the batch and the TCA Registry itself.
Enter the batch that was imported with batch de-duplication.
