This node reorders input work items based on one more attribute values. The attributes are used to create a tuple that identifies the work item and determines its new index. The ordering of values in the Attributes to Sort By multiparm determine the order that attributes are inserted into the tuple.

For example, consider 3 work item with the buildingnum and floornum attributes. The first two work items both have buildingnum = 2, and floornum = 0 and floornum = 1 respectively. The third work item has buildingnum = 0 and floornum = 0. By specifying “buildingnum” as the first attribute to sort by and “floornum” as the second, the items would would be sorted in the order they were originally in. If “floornum” was put first and “buildingnum” second, the items would be reorder so that the new order is 3, 1, 2 instead.
