Relating substitute parts

If there are dependencies between substitute part selections, you can relate the substitute part of one occurrence with substitute parts of the other occurrence. You can define these relationships for any occurrence in any BOM view revision. Such relationships are bidirectional. For example, you can relate substitute A of the lower bearing in the product structure to substitute B of the upper bearing, if the selection of B depends on the current selection of A. The same dependency applies to the selection of B as the upper bearing; that is, A must always be the lower bearing if B is selected as the upper bearing, and B must always be the upper bearing if A is selected as the lower bearing. However, Teamcenter does not enforce this relationship, if you choose to override it in a particular structure configuration. To relate substitutes, you must have write access to the parent BOM view revisions of the selected lines. If you do not have permission to modify either of the parents, you cannot relate the substitute parts.
