We need a designation similar to the gathering part designation that would allow us to designate an assembly as a purchased item so when displayed in the BOM it does not indent below the purchased item even thought there may be structure under that assembly node.
The reason is assemblies change from Make to Buy or Buy to Make all the time depending on plant capacity or capabilities. When suppliers or design partners provide an assembly in native cad it has the assembly part structure under the assembly node that is not required to be displayed when reporting on the top level assembly or when integrating with MES or ERP. If Auto association is used with WTParts and CAD the below structure will indent in Windchill. These sub-assemblies and parts are not required for integration or viewing in the BOM structure and currently there is no way of eliminating them.
