Refresh in the OfficeReports Ribbon Tab

Refresh Report

Clicking 'Refresh->Refresh Report' will update all links to Excel ranges defined on every slide in the presentation. So after setting new filters for the tables created in the workbook, you can refresh the workbook, and afterward the presentation. If you have to this multiple times, please have a look at 'Repetitive Reports' to create many workbooks, and then have a look at 'Repetitive Reports' in PowerPoint to create many presentations.

Refresh Slide

The same process as 'Refresh Report', just for the selected slide.
