SAP Business Client: Open URL in a new tab (GOS)

Hi!

I need to create a GOS (generic object service) that would generate an external URL and open it in a new tab of Business Client - I need to open a linked object in an external system. I have tried different approaches and all I get for now - my URL opens in IE and not in BC "in place".

Maybe anyone could advise on what tools to use in order to open generated URL in a new tab "in place" in BC.

Thanks.
