When you use a detail filter to filter a report only on detail data items, none of the data items in a detail filter are summary data items. Examples of detail data items are product, order number, and customer name.
• When going for a detail filters the filters are applied on individual data items in the report.
• You can filter detail data items that you select from a query or a catalog.
• Detail Filter --we can apply to each and every record in a database.
• A detail filter applies one or more specified conditions to each row of data. If the conditions are true for a row, the row is retrieved and appears in the report: if the conditions are not true, the row is not retrieved and does not appear in the report.
