2. Working with Teamcenter data types

2.1 Basic Teamcenter Data Types

Symbol	Description
	Item or “FFG Engineering Item”
	Item Revision or “FFG Engineering Item Revision”
	Assembly structure in folder form
	UGMASTER Dataset (NX 3D Model)
	UGPART Dataset (NX 2D drawing)
	BOM View (on item)
	BOM View Revision (at item revision)

2.2 Items and revisions

In Teamcenter, a part is referred to as “Item” (English) or “Element” (German). There can be different types of items, which can have different business rules, attributes, permissions, symbols, and so on. In this project the item type “FFG Engineering Item” was introduced for FFG, marked by a blue icon. This type contains, for example, the rules for assigning the item ID in the form “X.nnnn.nnnn” or “T.nnnn.nnnn”.

All geometric and non-geometric parts are represented as item type “FFG Engineering Item”.

The item contains those properties that are the same across all revisions and must be the same, such as the item number (item ID). The item always has at least one first revision (FFG revision 00). Further revisions (01, 02,…) can be created as soon as the last revision has been released and received a status.

When “unfolding” an item in the navigator, all revisions are always displayed.

2.3 BOM Views and BOM View revisions

In Teamcenter, structures (“BOM”) are stored in a separate object, the so-called “BOM View” or the “BOM View Revision”. If an item has a “BOM View”, then it is generally an assembly, otherwise it is an individual part or a component.

The “BOM View Revisions” are attached to the revisions and contain the BOM configuration of this revision. The “BOM View” is appended to the item and points to the last (current) “BOM View Revision”.

Assemblies are usually created using the CAD tool “NX” in Teamcenter. It is important to note that NX internally stores its own assembly information in the part file and that this must always match the information in Teamcenter. Improper editing of structures in Teamcenter can lead to an assembly not being loaded correctly in NX.
