How to focus Parent Window while closing the child window.

Hi,

In my scenario when i copy the Phonecall another copied Phonecall will open.

When i SaveAndClose this copied(child) form the Project form is opening from that.

I wrote javascript for window closing.

Xrm.Page.data.entity.save();

Xrm.Page.ui.close();

But, it doesn't work for that. Setting  Parent Window Focus may work.

Thanks.
