JDE Payroll 9.2 - Accrual Vacation DBA Calculation

Dear Community Members,

We are on JDE Payroll 9.2. We are enabling Vacation Accrual DBA for all Salaried Employees in March Payroll. This DBA uses Calculation Table which will add 16 Hours of Vacation time to each Employee from this month onwards. However for months of Jan and Feb 2022 the same 16 Hours each need to be added. Should we add 32 Hours for Jan + Feb to 16 Hours of March 2022 by making change to Calculation Table so it calculates 48 Hours in March and from April make it calculate 16 Hours every month?

Any method which will update History Vacation Hours for Jan and Feb months 16 Hours each?
