A report is therefore not the final output document (e.g. a PDF file or a Microsoft Excel Workbook) but a set of information that describes how such an output file shall be created. #### Report Document A report document is the specific output when a report (see above) is created (e.g. a PDF file, a Microsoft Excel Workbook etc.). > **Example:** A PDF file created from a Microsoft Word Report is a report document.
