• When updating hireStatus from ready to hire to hired through external HRIS integration, the process fails.
• Error code: ONB0006.
• Error message: “The request could not be completed because the value provided for personIdExternal already exists in the system. Please provide an unique value.”

SAP SuccessFactors Onboarding

Including personIdExternal and/or assignmentIdExternal in the UpdateFromExternalHRISOnb payload when a corresponding record already exists in Employee Central causes a duplicate-external-ID conflict, resulting in ONB0006.

1. Review the payload sent to UpdateFromExternalHRISOnb for the hireStatus change.
2. Remove personIdExternal and assignmentIdExternal from the request if the person already exists in Employee Central.
3. Include only the mandatory parameters in the request: onbStableId, sourceOfRecord, hireStatus, username.
4. Send the request again and confirm the hire status changes to hired without errors.
