In addition, sub-reports are fully supported. - A wide range of band types allows creating any kind of report: list, master-detail, group, multi-column, master-detail-detail and many more. - Wide range of available report objects: text, picture, line, shape, barcode, matrix, table, checkbox. - Reports can consist of several design pages, which allows reports to contain a cover, the data and a back cover, all in one file. - The Table object allows building a tabular report with variable number of rows and/or columns, just like in MS Excel. Aggregate functions are also available. - Powerful, fully configurable Matrix object that can be used to print pivot tables. - Report inheritance. For creating many reports with common elements such as titles, logos or footers you can place all the common elements in a base report and inherit all other reports from this base.
