The book fails to note an important limitation in Excel's Grand Totals feature, which doesn't work properly with calculated fields. In this example, Excel actually calculates Sum(UnitPrice)*Sum(Quantity), when the calculation it *should* be performing is Sum(UnitPrice*Quantity). There is no simple Pivot Table or calculated field setting that can change this behavior. Instead, the most common and reliable option is to add the calculated field to the table of source data, and then use that field to make row and column totals. If you are taking your data from a worksheet table, adding this calculated field is easy enough; if you are taking it from a database, you'll need to modify your query so that it generates the calculated column. Another, different option is to use the calculation options in Power Pivot.
