I have a multi user custom field called "System Owners" and I want to write a filter that will pull back any issues where any members of the System Owners field are not in a certain group. I tried the below JQL.
"System Owners" not in membersOf(the group)
At first I thought this was working because I got results, but then I realized that I think it is only showing issues where ALL of the people in "System Owners" are not in "the group". I would like to find a way to report where any of the users in the multi-user field are not in "the group". Does anyone have any great ideas for this? Or is it just not doable with built-in JQL?
