Hi @Keithschug,
@Amit_Shil has provided a good hint on a possible option.
Unfortunately, it seems that the community formatting has changed the code slightly.
Aggregate(
Except([Assignee].[User].Members,
Filter([Assignee].[User].Members,
[Assignee].CurrentMember.Name MATCHES '.*[X].*')
))
Martins from the eazyBI support has also provided another option that retrieves the user activity data from the Jira via SQL query.
You might read that here Filter on active user - #7 by martins.vanags.
