Hello rpseekell,   Unfortunately there is not a report just like that. A Service tag can have 1-3 warranties, and in some cases like Keep Your Harddrive or other add-ons could have upwards of 5 or 6 entitlements.    The report is going to pull all of those as separate line item since they are separate entitlements.  No report will aggregate them to one device per line item.  Maybe you can try export to Excel and manipulate the information to show what you want.
I'd like to use OpenManage Enterprise to show all our blade servers by name and when their (last) warranty expires. An Excel file would be great.  How would I do this? When I look at the devices showing name, IP, type, etc, I don't see warranty expiration.  When I go to the warranty page, I see name, model, etc and days left, but I have multiple lines per system (initial vs. extended) but I simply want one line per server with the date (or days remaining) of the last warranty. Thanks in advance.
