Hi Karl

Make sure after configuring all the settings you should capture the changes from the Dashboard which is Data collection update-> Collect data now, It will started automatically and after success you can able to see the reports in the report tab

Note: Make sure the report you are selecting consisting some information of changes in AD.

For Example : If you are selecting recently created user and there is no user created in that time period it will show you no data available

Thanks
