Crystal Reports Viewer is a scaled-down version of the business intelligence software application Crystal Reports. Both are produced by SAP. Crystal Reports Viewer allows you to view Crystal Reports data files, but you can edit the files only with the full version of Crystal Reports. As with all Microsoft Windows-based software applications, you can scroll vertically and horizontally in Crystal Reports Viewer by using your mouse.
Double-click on the Crystal Reports file, which should automatically open in the Crystal Reports Viewer.
Scroll your mouse wheel up and down to move the Crystal Reports page up and down. This is the quickest method of scrolling the page vertically.
Point the mouse cursor at the scroll bar at the bottom of the Crystal Reports page, click and hold the mouse button down, then drag the mouse left or right to scroll the page horizontally.
