3310727 - Duplicated records after MDF Data Import job


New records created after MDF Data Import job.


SAP SuccessFactors HXM Suite

Reproducing the Issue

Steps to proceed with the Import:

  1. Go to Import and Export Data
  2. Select Import Data
  3. Click on Zip File
  4. Choose the file to Import
  5. Click on Import

The same issue can happen when the import is done via Provisioning


When you use the external code on the MDF object as 'Auto Number', there is no validation, it means, everytime the same file is imported, new records will be created.


To avoid duplicate records, make sure not to use 'Auto Number' as external code on MDF object.

This change can be performed on Configure Object Definition.
