On the app i'm currently developping, I have several hyperlink to standard sap backend transaction such as BP, PDL and so on. i'm opening them by means of CrossApplicationNavigation. they open new tab.
on my main app, I implemented a button to close every tab and returning to root view.
I tried the following : Script to close other tabs or browser
here is my code :
            var oCrossAppNavigator = sap.ushell.Container.getService("CrossApplicationNavigation");
            var oExtUi = oEvent.getSource().getText();
            var hash = oCrossAppNavigator.hrefForExternal({
                target: {
                    semanticObject: "ZSIMM_PDL",
                    action: "display"
                },
                params: {
                    "UtilitiesPDL": oExtUi
                }
            });
            var url = window.location.href.split("#")[0] + hash;
            this._oComponent = sap.ui.component(sap.ui.core.Component.getOwnerIdFor(this.getView()));
            this._myModel = this._oComponent.getModel("oModelWindow");
            this._myModel.setProperty("/Window", window);
            sap.m.URLHelper.redirect(url, true);
        },   
this way, i open the new tab with my semanticObject. and I register it in my Model.
the next step is the method linked with my button :
            this._myModel = this._oComponent.getModel("oModelWindow");
            var aWindow = this._myModel.getData().Window;
            aWindow.close();    
I'm loading the window of the tab I opened. the instruction close doesn't work it writes : "Scripts may close only the windows that were opened by it."
what I understand in CrossApplicationNavigation is that it opened a new tab and redirect by use of sap.m.URLHelper.redirect(url, true); does the current screen before calling the new one know which page it opens ? and this way is there a method to close it manually ?
