Define the ActionDefinition Element for the Generate Change Actions Action
This will define the Action Definition element for the Generate Change Actions action.
As detailed above, locate the <ExplorerElementGroup> element with a sub-element <LogicContext> with the application attribute value of 'ptc.pdm.ProductStructureExplorer'. After the LogicContext element, add an ActionDefinition element like the following:
<ActionDefinition id="mycom.wnc.exp.GenerateRequirementsAction"
actionClass="com.ptc.windchill.explorer.structureexplorer.panel
.actions.GenerateChangeActionsAction">
<Action/>
<Import id="ptc.wnc.exp.IsValidInAllVAL"/>
</ActionDefinition>
* 
The id attribute defined in the <ActionDefinition> must match the import id defined for the GenerateReqsMI menu item defined in PDMLinkExplorerMenusForRequirementsTab.xml.
