Need to update Applicants Record through API

Hi

How to update applicants records in PER_ALL_PEOPLE_F table like last name,first,dob,email address fields.

hr applicant api => This API doesnt have Update procedure

hr_person_api.update_person => Employee no is INOUT parameter where applicant will not have empno.

The fields are updated through person screen as I tried for one applicant.

Is there any other API/method to update applicant details in EBS Release 11.

Thanks
