Business rule: Handle deleted event rule When set to true, the rule turns on the empty-events calculation setting; otherwise, it leaves that setting unchanged. The property is read with a default of false, so the calculation is not turned on unless the property is explicitly set to true. /sys_script.do?sys_id=b361607093110200eb19f179077ffbda

The default is false, so it is disabled unless an administrator enables it. /sys_script.do?sys_id=8bcbce209312020056f8f179077ffbff
