Hi [NAME],   Thanks for the feedback. I've not tried running a report as I don't have a test environment to try on. But if you run a report on License Report, OpenManage Enterprise > Monitor > Reports > License Report; are you able to see if the iDRAC license tracking are displayed?    If not available, what you can also do is to contact the OME support with a valid server service tag, you can submit a feature request through support. 
I just discovered OpenManage Enterprise and think it's great! This might be a feature request, but can we get iDRAC license information for our servers? It might be something we want in the Devices tab in the All Devices table.  Some of our servers have the Express, while others have the Enterprise, and it would be really nice to have this information in OME without tracking them in a spreadsheet, just so we know what needs to be upgraded.
