The variances may have occurred due to the selection of an incorrect distribution method. To resolve this, please do as follows:
Go to Leave module, Setup, Leave Type, Leave Type ID select Annual
At the Entitlement tab, change the Distribution method from Last Full to First Full
Click on Process Leave, Recalculate for all employees
Go to the ePortal, and go to System Settings, Tools, Sync
Note:
First Full — This method grants full leave entitlement in the first period onwards. For example, the entitlement is 14 days. In period 1, 14 days are available to the employee
Average — The total entitlement is divided equally every month. The balance is placed in the last month.
Last Full — The inverse of First full. The entitlement is placed in the last period.
