After adding annual plan for employee, and run calculate accrual for selected plan on (Absence records) page, an error shows indicating that variable L_ACCRUAL is used before being initialized. We modified the beginning of fast formula and tried many values for this variable, however, same error keeps showing and so no balance is calculated for employee. Also we tried modifying other parts of this formula however nothing changes. This error also shows in another issue for another plan, as this variable is used as well showing same error message when calculate accruals has been run.
