Compensatory Off Restriction

We have configured Compensatory Off using DFF and it should be utilized in next 60 days. However, employees can able to apply the compensatory off in past days. How to restrict compensatory off should be applied in Future Date? Please suggest.

We have included the below condition in Value Set:

(absent.absence_type_id=300000065868940 OR absent.absence_type_id=300000015675314)

AND absTypes.absence_type_id = absTypesTL.absence_type_id

AND absent.absence_type_id=absTypesTL.absence_type_id

and absent.ABSENCE_STATUS_CD='SUBMITTED'

and absent.APPROVAL_STATUS_CD ='APPROVED'

and ppf.person_id = absent.person_id

AND ppf.person_id=abse.person_id
