Navigation not enable after extending fiori app using WEBIDE

Hi everyone,

I have successfully extended the PO Approval App using WEBIDE.

But now the navigation/when clicking at item list, it does not work.

While in the standard PO Approval App, when clicking at item list, it will open the item detail.

I saw an error in using  Chrome browser saying that "segment {SAP__Origin} is required."

Can any body help me to tell what does it mean?

Thanks and Regards,

Tj
