A Parent-Child Item Association requires two Items:

The first Item must be serialized and is the parent Item in the relationship.

The second Item must be non-serialized and is the child Item in the relationship.

The Parent-Child Association:

Makes non-serialized items serialized in the sense that they are now associated with an identifiable item.

Ensures that both items stay logically connected.

Ensures that both items become physically connected at the appropriate time in the manufacturing process.

Tracker allows the parent Item may have more than one associated child Item.

A parent Item and a child Item can be associated by request, whether they reside in the same tracking region or in separate regions.

The request must specify the:

Sequential tracking region in which the child Item resides.

Item type of the child Item (non-serialized).

Sequence location of the child Item in the region.

The following diagram shows how a serialized item and a non-serialized item form a parent-child association. When two items comes together during production, and then must separate for processing, they form a parent-child association. By forming an association, the two parts can come together later on in the production process for assembly.

Example

1	A monitor is serialized and becomes the parent item when it is joined with the base.
2	Drill region	A sensor reads the bar code on a serialized item.
3	Drill region	The monitor and base are joined to have holes drilled to match the two pieces.
		The base is non-serialized and becomes the child of the serialized item - the monitor.
4A	Monitor Inspection region	The monitor is separated from the base for inspection, but is still associated with the base as the parent item.
4B	Paint region	The base has been separated from the monitor to be painted, but is still associated with the monitor as the child item.
5	Assemble region	The Parent-Child association in the tracking system has placed the two matching pieces together for assembly.
