The Leave Without Pay that is in its own 'category' on the Wages, Adjustments screen is hard coded to stop leave accruals for the days entered as Leave Without Pay. This is not a Leave Type and does not show in ESS and it is not possible to show it in ESS.
Note: If you create a Leave Without Pay leave type in all your awards, then these will show in ESS but it will not stop leave accruals when dates are entered in this Leave Type.
