SAP SuccessFactors Onboarding

1. Go to recruiting.
2. Rehire the candidate in the system.
3. Getting the below error while initiate onboarding:

      User ID can't be created because it's in use.

Person - ID - external is mapped from recruiting.

RCM should not be passing the person-id-external. By design person-id-external will default to USERID.

If there is a set up rule to generate this ID as part of Onboarding then IDs will match.

In case of rehire candidates, a temporary USERID is created until the rehire match is verified, upon time, the previous USERID will be used. 

In case there is a third-party tool used to generate person-id-external then it should be included as part of the Onboarding process, and NOT passed from Recruiting.

It is recommended not to map person-id-external from recruiting.
