This issue usually occurs when no Leave Entitlement Group is assigned to the employee. Without a valid entitlement group, the system cannot load leave data, causing the AC Payroll App to close unexpectedly during leave application. Steps to Resolve the Issue: Go to Payroll > Employee Maintenance. Locate the employee and click the pencil icon. Navigate to Employment Details. At the Entitlement Group field, ensure a valid entitlement group is properly assigned. Click Save changes. Go to Human Resource > Leave Management > Leave Balance. Verify that the employee’s leave entitlement is displayed correctly. The employee should now be able to apply for leave in the AC Payroll App. Written by: Azirah (20250522)
