Define the <StructureAuthorDefinition> element for the association table
This defines the StructureAuthorDefinition element used by the AssociationTable.
1. Open the ExplorerStructures.xml file from the following location:
<Windchill>/codebase/config/logicrepository/xml/explorer/struct
ureexplorer
2. Find the section in the file where the structure author definitions are defined. After the last <StructureAuthorDefinition> element, add the following definition for the Requirements:
<StructureAuthorDefinition id="mycom.wnc.exp.RequirementSAD">
<Import id="mycom.wnc.exp.PartToRequirementSD"/>
</StructureAuthorDefinition>
* 
The id attribute for the <StructureAuthorDefinition> must match the id specified in the import sub-element of the <AssociationTable> element defined above.
