HI All
I think for the time being there is no such functionality on the SAP Launchpad to take a PDF copy which is utterly disappointing but then again they are improving the systems a lot and hopefully this will be available in future.
BUT LUCKILY I DO HAVE A SOLUTION TO THIS FOR NOW 
1. Select the content you want to take out on a PDF. i.e. Select the whole conversation along with the text where OSS number is written.
Do not Press Cntrl + A. Select by dragging your mouse over the content
2. Right Click on the selected text
3. Click Print
4. Save in a PDF Format.
5. Woooooh PDF will have the content you need.
I have tried this and have been successful every time 
Hope this Helps!
