I have checked the documentation regarding recalculations in time off and cannot see a specific mention on which business rule will be used for recalculating the balance Hire Rule or the Accrual Rule.
Can anyone please provide a link to SF documentation which mentions this information.
It depends on whether the employee is a new hire in the accrual period. If he started in the accrual period the new hire rule is used. If he didn't start in the accrual period the standard accrual rule is used.
The new hire rule should be coded in such a way that it can be rerun to calculate a correct accrual value in the hire period
unfortunately I have been through the help.sap.com documentation and the blogs, they all say what steps are needed and I have all the steps enabled and recalculation is working but the only issue is recalculation is using the Hire Rule to recalculate the balance.
In our case the Hire Rule and Accrual rule are different and we want the Accrual rule to be used for recalculation and not the Hire rule. None of the documentation or blogs are saying whether Hire Rule attached to the Time Account Type will be used for recalculation or the Accrual rule attached to the Time Account Type will be used for recalculation.
Did you look into those parts:
This guide have several chapters talking only about the recalculations, so you may find what you are looking for.
Additionally, take a look in the following blogs:
I hope this helps!
