vacation advance/ notice period recovery from employees guarantor

Hello Experts!

Our customer has the following requirements-->

1. When the employees goes on vacation he takes the vacation advance( which is paid via cheque and nullified in FI after he returns via payroll).

While apply for vacation he needs to specify another employee who will be his guarantor in case the employee does not return from vacation.

In such a case if the employee has any amount due to be paid to him...the vacation advance and notice period will be recovered from him...and if not then remaining vacation advance and notice period should be recovered from the guarantor. Recovery can be one time or in installments.

Please suggest how this can be achieved!!

Thanks,

Poonam
