Creating a new BOM view revision

When you add a component to an assembly, you are creating an occurrence of that item or item revision in the assembly, which is stored on the BOM view revision (BVR). This occurrence is displayed as a BOM line. A BVR is a single-level structure that contains occurrences of its immediate children. A multilevel structure is built up from many single line BVRs. Any modification to a product structure (including changing any of the occurrence attributes or adding a substitute) causes a change to the BVR of the parent assembly. If no BVR exists in the parent assembly, Teamcenter creates one automatically. When BVRs are automatically created in this way, they may be precise or imprecise according to your specified options; by default, imprecise BVRs are created. You can also create a new BOM view revision manually.
