===links.toGuid===
Another example of a special field available in iReport templates is the '''links.toGuid''' value. links.toGuid is available on any of the major objects in {{IMSMANG}} including Land, Activity, Education, Accident, Victim, Assistance, Location, and Quality Management. This field can be used in the Report Query portion of a report to filter the results based on linkages to other objects. For example, on a Land report with an Activity subreport, the subreport could contain the following Report Query filter to return only Activities with linkages to the Land on the main report:
links.toGuid = "$P{HazardGUID}"
As with other areas in iReport, the ''links.toGuid'' field is case sensitive and must be referenced exactly,
