second level routing work properly but  grand child routing not work. see attached screen shots

1) First level routing :  code in shell.js 

define(['plugins/router', 'durandal/app'], function (router, app) {

    return {

        router: router,

        search: function() {

            //It's really easy to show a message box.

            //You can add custom options too. Also, it returns a promise for the user's response.

            app.showMessage('Search not yet implemented...');

        },

        activate: function () {

            router.map([               

                { route: ['', 'viewmodels/Planning*details'], title: 'PRODUCT SELECTION', moduleId: 'viewmodels/Planning/productSelection', nav: true, hash: '#viewmodels/Planning' },

                { route: 'priceStrategy', title: 'PRICE STRATEGY', moduleId: 'viewmodels/Planning/priceStrategy', nav: true },

                { route: 'approvals', title: 'APPROVALS', moduleId: 'viewmodels/Planning/Approvals', nav: true },

                { route: ['', 'viewmodels/Execution*details'], title: 'Approvals', moduleId: 'viewmodels/Execution/approvals', nav: true, hash: '#viewmodels/Execution' },

            ]).buildNavigationModel();        

            return router.activate();

        }

    };

});

2)second level routing : code in ProductSelection.js

define(['plugins/router', 'durandal/system', 'durandal/app', './simpleGrid', 'knockout'], function (router,system, app, SimpleGrid, ko) {

    //var ko = require('knockout');

    var childRouter = router.createChildRouter()

           .makeRelative({

               moduleId: 'viewmodels/Planning',

               fromParent: true

           }).map([

               { route: ['', 'Composite_Score*details'], moduleId: 'Composite_Score/CScore', title: 'Composite Score', type: 'intro', nav: true, hash: '#viewmodels/Planning/Composite_Score' },

               { route: 'PricingPlaning', moduleId: 'Profile/PricingPlaning', title: 'Profile', type: 'intro', nav: true },

               { route: 'Price_Change', moduleId: 'Price_Point/Price_Change', title: 'Price Point', type: 'intro', nav: true },

               { route: 'Productlist', moduleId: 'Financials/Productlist', title: 'Financials', type: 'intro', nav: true }        

              ]).buildNavigationModel();

    return {

        router: childRouter,

        introSamples: ko.computed(function () {

            return ko.utils.arrayFilter(childRouter.navigationModel(), function (route) {

                return route.type == 'intro';

            });

        })        

    };

});

3) Grand chind routing: code in CScore.js 

define(['plugins/router', 'durandal/system', 'durandal/app', 'knockout'], function (router, system, app,ko) {

    //var ko = require('knockout');

    var childRouter = router.createChildRouter()

           .makeRelative({

               moduleId: 'viewmodels/Planning/Composite_Score',

               fromParent: true

           }).map([

               { route: 'Composite_Score/compositeScore', moduleId: 'Composite_Score/CS/compositeScore', title: 'Composite Score', type: 'intro', nav: true },

               { route: 'Composite_Score/Productlist1', moduleId: 'Composite_Score/CS1/Productlist1', title: 'Profile1', type: 'intro', nav: true },

               ]).buildNavigationModel();

    return {

        router: childRouter,

        introSamples: ko.computed(function () {

            return ko.utils.arrayFilter(childRouter.navigationModel(), function (route) {

                return route.type == 'intro';

            });

        })

    };

});
