Duplicate Sys Id fields are visible for Incident, Problem and Change tables !!SummaryDuplicate Sys Id fields are visible for Incident, Problem and Change tables under table columns in the table form view. Reason This is expected behavior, the tables like Incident, Change,Problem ..etc are flattened to one physical table 'task'.Please refer : Table flattening So you are seeing sys_id's one for the current logical table and one for the task table.To confirm that, add the field name 'table' to the list view using gear icon and check which table they are representing.
