I am still fairly new to Revive Adserver, so forgive me if this is a redundant question. I am the webmaster for a radio group of 8 radio stations and dealing with several different sales people. I am looking for a way to track available ad inventory on my websites. Is there a way to input the number of each zone I have on a website and generate some sort of report to show how many campaigns are running vs. how many spaces are available? For instance, if I have (4) 300x250 ad spaces on 1 webpage using 1 invocation code, is it possible to show how many campaigns are currently running to that invocation code and how many are actually available? I hope my question is making sense.....
