Fail to create a custom report
I'm having troubles with custom reports. It seems to be an easy task, I just wanna see violations of a single policy so I create new blank report, choose period and devices, add filters - Policy ID equal to 208 (btw what is the difference between policy_id and policyid? I tried both) and it seems to be all I need, right? But when I run this report it comes out just blank.
Is there anything else I need to configure? Do I have to add something on Layout page to make it work? Please help, I couldn't find any detailed tutorials, just do 1,2,3 and here are your report, that's what I do and it doesn't work.
