2504068 - Error with null or empty Per Person UUID in Check Tool (Check ID: NullOrEmptyPerPersonUUID / UserProfileUUIDValidationCheck)


When running the Check Tool for Employee Central Core or Talent Intelligence Hub, issues for the checks "Null or Empty Per Person UUID" (NullOrEmptyPerPersonUUID) or "User Profile UUIDs are valid" (UserProfileUUIDValidationCheck) can be found.

  • SAP SuccessFactors Talent Intelligence Hub


In 2016, the field "perpersonUUID" was added to the per_person table and its entity object to facilitate future suite integration. The perpersonUUID field is populated during the New Hire process with a unique and immutable id which is not available for reporting and is not exposed in any UI. For per_person records created prior to this change in 2016, the UUID field is empty. These empty UUID fields will be flagged as the user profile UUIDs must be valid and not a null value.


The check result is expected and has no impact on existing processes. To resolve the error, run the Initialize per person immutable id job in Provisioning. As a customer, you do not have access to Provisioning. Please engage a Certified Partner or Product Support to assist with this configuration.

To create a case with Product Support:

  • If the check is under Employee Central Core, please create the case under component LOD-SF-EC-PER
  • If the check is under Talent Intelligence Hub, please create the case under component LOD-SF-TIH-MIG
    • Please provide the below required details to process the job:
      • Data Center (URL of your login screen)
      • Company Instance ID (where to apply changes)
      • Username (for us to populate as the Job Owner)
      • Approval to run the job

Steps for Support or Certified Partners:

  1. Log in to Provisioning
  2. Select the company name
  3. Select Manage Scheduled Jobs
  4. Select Create New Job
  5. Populate the following details:
    • Job Name: person GUID
    • Job Owner: [username provided by customer]
    • Job Type: Initialize per person immutable id
    • Occurrence: Once
  6. Select Create Job
  7. Locate the job and under the Actions column, select Run It Now

After the job has been processed, customers can run the check tool again and the errors will be resolved.
