3623420 - [Error Code: 3] The provided username is already in use. Choose a different user name for Rehire candidate - Onboarding

• After Rehire candidate was initiated from Recruiting, an error was seen in Business Process tile [Error Code: 3] The provided username is already in use. Choose a different user name. 
• Candidate did not initiate on Onboarding Dashboard.

SAP SuccessFactors Onboarding

1. Initiate a Rehire candidate from Recruiting
2. Candidate did not reach to Onboarding Dashboard
3. Upon checking to-do dropdown and Business Process tile, we can see candidate appears with error: 
   1. [Error Code: 3] The provided username is already in use. Choose a different user name. 
4. Copy the Process Trigger ID
5. Go to Manage Data > Process Trigger > and paste the ID for the affected candidate
6. A incomplete profile appears, few information is available, but Rehire on New Employment is already triggered.
7. Now go to Data Inspector > Table_User_SysInfo > enter the user name being selected > note how there is already an entry for this user name, with valid field as 'f' (inactive employee).

When a candidate is onboarded as a rehire on new employment, a new username is generated. Issue is happening once Rehire is triggered as soon as it reaches onboarding side. System recognizes it as already in use as a previous employment exists for this candidate.

At this point, the system will not allow us to proceed using the same username again. What you can do as a workaround: change the Primary email in SuccessFactors Recruiting and then restart the task in BPE.

I'm providing you a KBA where you'll be able to proceed with the Primary Email change if needed for the affected candidates (we can run a script) 3423305 - Data Validation: "The User Name you provided is not valid.
