2391798 - UUID - Universal Unique Identifier not visible in the UI


The field "UUID" (id="per-person-uuid") is enabled in personInfo / Biographical Information portlet, but it is not visible in the UI.


SAP SuccessFactors Employee Central


  • In b1611 release, the new field "UUID" (id="per-person-uuid") was introduced for Suite Integration purposes. This is an Immutable ID, generated by the system when Person data is created.
  • When you import Biographical or Basic User information, the system now automatically create a unique identifier for each record. This is stored as the per-person-uuid field. The intention is that this ID can be used to integrate Person Data in Employee Central with other modules like Onboarding, Learning, Recruiting, Talent, and so on.
  • Currently cannot expose the field in the EC UI. You will only see this in the Import template for Biographical Information, as well as Ad Hoc / ODS Reports for Biographical Information. 



To view the per-person-uuid field value in the Biographical Information Import template, you must add the field to the hris-element "personInfo" in the Succession Data Model, and it must be configured exactly as specified - visibility="view" and allow-import="true". Please do not change any of the highlighted attributes -:

  <hris-element id="personInfo">
    <hris-field max-length="32" id="per-person-uuid" visibility="view">
      <label xml:lang="en-GB">UUID</label>

You can also add the field via the Business Configuration UI (Admin Center > Manage Business Configuration) -:

A) This is expected behavior. Currently the field is not displayed in any UI and there are no plans to do so.

Q) Why can I not see the field in the Biographical Information import template
A) The field should be configured as - visibility="view". It must not be set to Editable.

Q) Can I use the UUID field in Business Rules?

A) No - it's immutable and used by the system - this value is not expected to be customizable/manipulatable
