Structure Manager terms

The terms explained in this topic help you better work with Teamcenter and manage your structures.

Term	Description
Element or occurrence	An item or an item revision within the structure of a parent.
Baseline	A copy of the currently configured structure at the time the baseline was created. Baselining configures a structure and thereby guarantees that the structure is always the same as that when the baseline was created.
Release effectivity	A term used in manufacturing. You configure the structure for a specified date or unit (serial) number by applying a revision rule. Teamcenter shows the revision of each item that is in effect for the specified date, unit number, or range.
Occurrence (structure) effectivity	A term used by manufacturers in the military and aerospace domains. You configure the structure in a way similar to revision effectivity, and Teamcenter shows the actual occurrences that are in effect. Occurrence effectivity applies to the specific element's usage and not globally. It indicates when a child item is effective in the parent assembly.
Working context	A way to set your work aside and then pick up where you left off when you return. The saved working context captures the structure configuration with the context applied, including revision rules, effectivity, and variant rules. It also captures the current focus of navigation and any active selections.
Solution variant	A variant created to derive a buildable (100%) variant of a product that has variability. To create a solution variant, you apply a valid variant configuration to the variable structure. The solution variant has a unique item ID and is linked to the source structure.
Workset	A collection of design components. A workset can contain one or more structures, items, item revisions, BOM views, and BOM view revisions that represent existing parts or assemblies.
