You use a pivot table to keep track of product samples from each category that were sent to each sales region. You d like to enter the sample quantities in the Values area of the pivot table, instead of creating records in the source data. When you try to type in a cell in the Values area, you see the error message Cannot change this part of a PivotTable report. In the pivot table, the Region field is in the Row Labels area, Category is in the Column Labels area, and Quantity is in the Values area. This problem is based on the ChangeValues.xlsx sample workbook.
