FYI - I found some more stuff that might help. In the OC Report Install & Admin Guide p.46 has the following:

These 2 particular database views do appear to contain the data I'm after based on this:
[root@dfmserver ~]# dfm database query run "select * from commentNamesView"
"commentNameId","commentName"
"1","ownerEmail"
"2","ownerName"
"3","resourceTag"
"5","SecurityZone"
"6","wApp"
"7","Application Name"
"8","BUFG"
"9","CIFS AD Domain"
"10","Comments"
"11","Environment"
"12","Escalation"
"13","Fault Domain"
"14","Function"
"15","Maintenance Expires"
"17","Purpose"
"18","Remarks"
"19","Ship Date"
"20","Zone"
[root@dfmserver ~]#
[root@dfmserver ~]# dfm database query run "select * from objCommentView"
"objCommentObjId","objCommentNameId","objComment"
"957","2","David Cornely"
"957","1","david_cornely@intuit.com"
"790","5","SG"
"789","5","NG"
"1180","6","david"
"1180","1","david_cornely@intuit.com"
"1243","8","PDIT"
"1243","6","Helmet"
I don't have the Error Retrieving Data in OC Report so I'm not sure if I need to enable these DFM database views? I've been scouring the NOW knowledgebase, community and Admin guides for DFM but can't see how to enable them or even check if they are enabled or disabled. Thanks.
