Previewing the report lets you see how the OLE object displays the data from the report. You can preview in the Preview view or in preview mode
To preview the report with the OLE object in preview mode:
Select File>Run/Preview from the menu bar, or click the Run/Preview button on the PowerBar.
Select Rows>Retrieve from the menu bar.
The report retrieves rows from the database and replaces the initial presentation of the OLE object with an image of the data that the OLE server provides.
