Will deleting a creative from a playlist in Visiconn remove it from the Proof of Play reports?
The answer is No. By deleting content from a playlist or even the media library, this action does not remove the creative from the proof of play reporting database. You can even delete the advertiser (not recommended) and the reported data will still be in the report database. These reports are stored for 12 calendar months. So if the date trying to run a report for is past the 12 month year/date, there will be no reports available.
