The system OperaOpus is upgraded with the possibility of creating reports defined by templates in Microsoft Excel. Such reports are often defined by the legislator (e.g. quarterly and annual statistical reports, standard forms and the profit and loss account, balance sheet status and similar), foreign company owners (templates ready for consolidation at the level of concern) or user-defined (arbitrary position from the balance sheet). Reports are defined by link between the Excel cells that should be completed and the account through which the data from the main book is drawn. Reports can be obtained by periods (cumulatively or individually) with arbitrary lengths with a graphic view of the relation of individual positions.
