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

Content

Hello,

Requirement is to calculate /prorate balances as of date when the accrual process is run . Since Daily repeating period option no longer available, we are planning to use effective Date used to run Calculate Accruals Balances Process.

Is there any way to get this effective date instead of using system date?

GET_CONTEXT(EFFECTIVE_DATE) is returning the accrual period end date, when we use other repeating periods like weekly / monthly /Yearly

Requirement is to allot initial accruals based on Length of service  and prorated hours if any promotions / transfers occur.
