About data precedence

You can associate data with an item revision or absolute occurrence. You can create the absolute occurrence in the context of a top-level item.

The following figure shows how visualization (JT) files may be attached to items.

Attaching visualization files to items

In this example, you can see file1.jt in the viewer in My Teamcenter without any context. However, when you view the same item revision (ItemRev1) in the context of TopItem1, you see the JT file (file2.jt) that is associated with the corresponding absolute occurrence (appr1) in the context of item TopItem1/A.

You can associate a different JT file as an override if TopItem1 is revised from revision A to revision B.

Data is associated with an absolute occurrence in the context of a specified revision. When you revise an item, the data associated with the previous revision is copied and you can change it as necessary.
