LEAVE_REASON_REQUIRED is an optional toggle field. If this toggle is ON, the leave reason will be required only when leave is entered through the IAAL, IPTS and IPTR screens. If a leave is entered in the IPPH or Time Exceptions screens, it will not be required even if this toggle is ON. For the IPTS screen, there is a 'Show Require Leave Reason' button that displays a dialog box where the user can enter the leave reason. For the IPTR screen, the leave reason can be entered on the Time Code Tab. If this toggle is OFF, the Leave Line Details pop-up box will only appear when the time warning rule is invoked.
