How to get the effective date used to run 'Calculate Accruals and Balances'?

Content

Hi,

       For one of our requirement we have to use the effective date parameter's value of calculate accruals and balances process in Global Absence Accrual Matrix Formula. I thought the context value "EFFECTIVE_DATE" of this formula will provide what i was looking for but actually it provides the accrual period end date value.

Is there any way to get the effective date parameter value of calculate accruals and balances process in the Global Absence Accrual Matrix Formula?

 

I specifically want to use the effective date passed on while running the accrual process.
