PreTax Deduction Element -Proration is not working

Hello,

We have a PreTax Deduction Element defined.

During payroll, if there is a cahnge in the value for AMOUNT in the middle of pay period, the proration doesnt work properly.

As a solutiom, we have created the seeded proration group and attached a custom Proration formula.

But still the pro-ration is not workimng properly.

CUSTOM FAST FORMULA:( As per Oracle suggestion)

Default for pay_value is 0

Default For PAY_EARNED_START_DATE Is '1900/01/01 00:00:00' (Date)

Default For PAY_EARNED_END_DATE Is '4712/12/31 00:00:00' (Date)

Inputs are pay_value,

prorate_end (Date)
