Get absence Periodic accrual balance in Fast Formula

Content

Hi All,

 

I have a required to call the previous year's absence Periodic accrual in carryover Fast formula, based on the previous year accrual the current year carryover is determined. can someone suggest how to get the Periodic accrual in FF.

1. I cannot use IV_ACCRUAL because i am using the accrual formula to calculate the accrual
2. I cannot use GET_PLAN_BALANCE OR GET_ACCRUAL_BALANCE because these functions will always return total balance as on given date, not just the Periodic accruals 

Thanks
