+There are instances where groups are created but remain without members for an extended period, making them ineffective.
+This script helps identify such groups that have no members within a specified timeframe and make them inactive.
+
+Scenario-
+Deactivate the active groups which doesn't have members for last 6 months.
+Approach-
+1. A scheduled job runs daily or weekly to identify groups without members.
+2. To track when a group becomes memberless, a Date field (e.g. u_memberless_date) is added to the sys_user_group table and populated with the current date when no members are found.
+3. If members are added later, the field value is cleared.
+4. Groups that remain memberless for over six months (based on the u_memberless_date) are automatically deactivated.
