Open another weblink from CRM UI

Hi Guys,

I am trying to open new webpage (like google.com etc) from CRM UI. Actually my requirement is to open in pdf image of an invoice from CRM.

When user click on the invoice it will bring the PDF image URL from ECM.

I tried the function module CALL_BROWSER. It is working from GUI but not from UI.

Could you help me on this.

Thanks in advance.
