I recently signed up to enable YouTube revenue sharing on my search videos. It was part so that I can try to get my YouTube videos into Google News (still working on that).
One thing I noticed was that while my AdSense reports update daily, my YouTube data in the AdSense reporting tool shows "no data available." I then spotted a thread about this "issue" today at Google AdSense Help. I dug around and noticed that this is by design.
YouTube earnings are documented to be 30 days back dated. So the YouTube earnings will first show 30 days after the previous month, for that previous month and then it would be paid out 30 days after that, if you have $100 of earnings or more. Google said, "AdSense for Content Host revenue is paid 30 days after the month's end. "YouTube" includes revenue from ads placed next to your videos. YouTube revenue is paid 60 days after the month's end."
