HRIS-SYNC mapping configuration in Succession Data Model : 3066117 - How to export Data Models?

If you find the below configuration on the Data Model,

 <hris-element-ref refid="personalInfo">


        <hris-field-ref refid="custom-string3"/>

        <standard-element-ref refid="defaultLocale"/>




It means the data source is EC field custom-string3 in <hris-element-ref refid="personalInfo">, it will override the standard element defaultLocale.

That's why the language is updated back to English US.


Note: using custom-string3 as an example in this case

Please note that if personalInfo.custom-string3 is empty, en_US will be the default value.

We do not recommend and support above configuration.

To resolve this issue, either remove that Hrsis sync Mapping configuration or maintain desired language data in EC field custom-string3.


  • Step 1: Run full Hris Sync then export (UDF file or Employee Export)
  • Step 2: Backup (UDF file or Employee Export) into your desktop
  • Step 3: Remove wrong mapping code VIA BCUI or 3066117 - How to export Data Models?
  • Step 4: Run Full hris sync
  • Step 5: Export UDF and compare with Backup (UDF file or Employee Export) and correct all mising default local Via Basic import

If you use above configuration, custom-string3 must only be filled according to KBA 2269945 - List of Supported Languages with Locales for SuccessFactors


  • EC Field: custom-string3 = NO Record or Empty
  • The system will default: EP standard-element-ref refid="defaultLocale =  en_US
  • Result: This expected behavior.
