Understanding change objects

You can create a change object to control changes within a collaboration context. The change object affects the structures shown in the collaboration pane and each structure pane. You can configure different effectivity dates or numbers for each of these panes with their revision rules. Any attachments to the structure are also affected by these revision rules.

You can make changes to any structure by adding an occurrence to it or removing an occurrence from it without creating a new revision through these incremental changes. The change object is identified by a unique change ID. The change ID is an effectivity identifier either in terms of a date or a serial number. Serial numbers are identified with an end item.

You can attach more than one change object for the same type of change to a structure. For example, you can attach a new dataset associated with the first change order, which is effective from 1-March-2011 to 30-March-2011, you can later add another dataset for a second change object of the same type, which is effective from 1-June-2011 to 30-June-2011. Teamcenter prevents you making duplicate changes by attaching the same change object more than once.

You can also create a baseline item revision by configuring all the incremental changes.

A single change can add or remove multiple objects from an item or item revision. A single object can be added to an item or item revision with different effectivities by several changes, and removed with different effectivities by several other change objects.
