e-Recruitment how to delete application or withdraw?

Dear Experts,

I have an issue in SAP e-Recruitment 6.0 EhP4 BSP.

Recruiter entered an application for an internal candidate by mistake and rejected him.

Now the candidate sees from candidate page - Applications that his application was rejected, complaining that he had never applied to this posting (which is true) and does not want to have it in his application history.

We advised the candidate to withdraw the application but the error "The application cannot be withdrawn" appears and he could not withdraw or delete the application.

Is there a way to completely delete application or at least to withdraw it?

Thanks in advance.

Regards,

Emi
