Kathy -
I worked with a client in the past on this issue, because this information isn't easy to get to (or accessible at all) we built a series of dashboards tracking volume of licenses given out (by department/team), number of users who had log in time tracked in Eloqua and then we made some assumptions around the types of data pushed to Discover/Profiler and you could filter that by Sales Rep if you're pulling ownership of data back into Eloqua from your CRM. It was not exactly the full picture but it was better than nothing. Michelle Ison any commentary you can provide, I know it would give some good info for Kathy
Best,
Lauren
