Change Page Title of embedded DS reports in the portal

Dear all,

we have our Design Studio Reports embedded in the Portal. The title of the browser window is the title of the navigation entry you are navigating to.

We have a demand where we need to overwrite the title from within the Design Studio Report to add a specific pattern to the title of the browser.

as an Example:

Name of the navigation entry: Report XY

Current browser title: Report XY

Target browser title: [DS] Report XY

I know from the ABAP Web Dynpro and CRM WebUI that there are standard functions to influence the title with customer code, when they are embedded in the portal.

Is there any way (hopefully without the use of the SDK) to influence the browser window title from Design Studio Reports when embedded in the Portal?

Thanks a lot and best regards

Fabian
