How to user Reporting To field in service desk plus

Hi,

How can I fill data in Reporting To field ?.

Recently I upgraded my version to    8.2.0  Build 8217.      from 8.2.0 Build 8206. 

I am fetching data from active directory directly. 

Kindly explain the method to fill Reporting To if it is not possible from AD.
