Scrollbar options are only available when an embedded object is view only. Scrollbar properties on the Object tab determine how and when they are displayed: The horizontal and vertical scrollbars can be used to scroll only the current page of the original section
If the Show Scrollbar option is set to always, vertical and horizontal scrollbars are displayed adjacent to but outside the container boundaries of the sections and do not obstruct them.
If the Show Scrollbar option is set to never, vertical and horizontal scrollbars are not displayed.
If the Show Scrollbar is set to automatic, The horizontal and vertical scrollbars appear when necessary and not as a default.
If Auto-Size is enabled, the object data is scaled to fit within the container boundary of the section, and the object cannot be scrolled. This means only the first page of the report is displayed. Disabling the autosize option makes the scrollbars active.
