How to restrict FD for an absence plan from getting retrigged for terms

Summary:

We are seeing an issues for termination where the final disbursement is getting retriggered few days after the person is terminated resulting in over payout.

For Paid time Off whenever there is any update happening on absence entries side for terminated associates the FD is getting retriggered again.

We are already using person selection Fast Formula to exclude the terminated associates while running the Calculation Accruals and Balances job. But the accruals and FD us getting calculated automatically whenever there is any absence entry update.

Can you please let us know if there is anyway to restrict the FD from getting retrigged for the terminated associates?
