    <entity name="incident">
        <attribute name="title" />
        <attribute name="ticketnumber" />
        <attribute name="createdon" />
        <attribute name="incidentid" />
        <order attribute="title" descending="false" />
        <link-entity name="serviceappointment" from="wl_serviceactivitiesid" to="incidentid" alias="aa" link-type="outer">
            <filter type="and">
                <condition attribute="wl_serviceactivitiesid" operator="null" />
            </filter>
        </link-entity>
</entity>
