This results in the attributes being requested in the Wizard and Information Tab as shown in Section Intended Outcome.
To add the reusable attribute to the Uses Tab, edit:
Windchill>/codebase/config/logicrepository/xml/explorer/structure
explorer/ExplorerForTablesAndPanels.xml
Locate the Table entry with id ptc.wnc.exp.PartUsesLinkTabTable and add:
<CellDefinition id="myColor" displayModeOverride="edit">
<AttributeDefinition attributeId="com.aprilia.www.myColor">
<Import id="ptc.wnc.exp.AssocAttrAction"/>
</AttributeDefinition>
