Minimizing structure expansion

When you configure task page structures, you can use expansion rules to minimize expansion of unecessary structure lines just as you do in Manufacturing Process Planner. For example, you may not want to expand an assembly if it is time consuming, if it is outsourced to a third party, or if it is not assigned to a current project.

Expansion rules are a type of closure rule. Expansion rules specify which lines in a structure should not load or expand when specific relationships are encountered. You can apply expansion rules to all structures except for a production program. That is, you can apply expansion rules to an engineering bill of materials (EBOM), a manufacturing bill of materials (MBOM), a product bill of process (BOP), a plant BOP, and a bill of equipment (BOE). Administrators can create predefined or custom rules in Teamcenter Manufacturing Process Planner using the preference ClosureRulesForBomExpansion.

In the following example, the closure rule BOMExpandSkipByPartSource, which is available by default in Manufacturing Process Planner, contains a condition that declares that if a secondary object type of Part exists in a BOM structure, and the primary part source is equal to Make, then the action type SKIP is applied to the structure.

The example below shows an EBOM structure before and after the BOMExpandSkipByPartSource rule is applied. All parts with a part source equal to Make, such as Part2 and Part4, are excluded from the structure. All assemblies that contain parts whose primary part source is equal to Make, such as Item2, Item3, and Item4, are also excluded.
