Dear Azury,
Thankyou for your response.
Your solution is perfectly sound for fulfilling the purpose.
However, because I am conducting a demo, I thought a reporting set restriction on the main screen would be more appealing, than an additional selection screen.
In a demo screenshot I have seen that the restrict by option "Persons along organizational structure", is listed right under "No. of hits" like in my screen shot. Can you shed some light on that. I am attaching the demo screenshot I am talking about for reference as well
Thanks,
Talha
