Duplicate Supplier - Interviewee candidate as Supplier Converts to Employee as Supplier

Hi Team,

We are working on a business problem in which the challenge is to avoid creation of Duplicate Supplier in the system.

The scenario is:

1) A candidate appears for the interview and he is created as a Supplier with vendor type as "Interviewee Candidate" so that all expenses could be reimbursed to the candidate.

2) In the eventuality of candidate being selected, he joins the firm and his records are created in HRMS as an employee.

3) Challenge:

(a) Now, if this employee is created as Supplier - then there shall be duplicate supplier in the system.

(b) If the previously created Supplier is being edited for Vendor Type - system doesn't allow Vendor Type to be selected as 'Employee'
