A record marked “duplicate” can be a few different things. Remember, in case management, one individual = one case. If the same vulnerable individual (usually a child) is registered more than once in the system, they will have more than one unique identifier. This is a problem, since we want a single case manager to take responsibility for ensuring care for that individual. So, if a system user manually marks a record “duplicate” it usually means they - or their sys admin - have discovered that the same individual has multiple records. Marking the record “duplicate” does not erase it, but the default case list view (and reports) only displays records marked “open”.
