In Discover XI, a group can legitimately have 0 members if it was emptied manually (for example via a batch action) or by an automated process such as an update rule.

This article focuses on customer-actionable checks you can perform in the Discover XI UI to determine why a group is currently empty and how to prevent recurrence.

Solution

1. Confirm you are looking at the correct group (and that it still exists)

   1. Navigate to People → Groups.
   2. Search for the group by name and verify its status (for example, whether it was archived).
   3. If the group is not listed, it may have been archived or deleted. (Both actions exist in the Groups UI.)

2. Check whether an update rule is configured for the group

   1. In the Groups area, open Update rules (documented path: People → Groups → Update rules).
   2. Locate any rules targeting the affected group and review their configuration, including whether they are set to run automatically and when they were last executed automatically.
   3. If appropriate for your use case, use Apply Rule Now to run the rule.
   4. If you need step-by-step guidance on configuring grouping filters and update rules, refer to [2].

3. Look for actions that can empty the group

   Update rules can include actions such as Empty group and Apply grouping filter. Review the actions configured in any rule targeting the affected group.

4. Optional: enable monitoring to track group size changes over time

   1. Edit the group and enable the option to mark it as a monitored group.
   2. Review group-size development in People → Statistics → Panel overview → Group history.

5. If you still cannot determine the cause, contact Support with the following

   • Instance URL
   • Group name and (if available) group ID
   • Approximate timestamp range (with timezone) when you last saw the group non-empty
   • Whether an update rule exists for the group and, if so, the rule name and last execution time (from the Update rules overview)
   • Screenshots of the group showing 0 members

If the customer provides timestamps and group identifiers but cannot explain the emptying via UI configuration (update rules/batch actions), use internal troubleshooting paths to correlate the time window with platform logs.
