Symptom
Is it possible to use Auto-Number ExternalCode for MDF Objects Import?
Environment
SAP SuccessFactors HXM Suite
Resolution
There are some limitations that can be found on: SAP Help Portal Auto-Number ExternalCode for MDF Objects
Currently, Instance Sync will not work reliably for objects with Auto-Number external code.
Note: the limitation is related to setting external code of an parent object. The scenario for child objects as auto number is supported. So it is expected that using auto number in the external code of child objects will allow you to import and edit the records successfully while it would fail for parent objects.
