Question:  How do I remove subtotals on a pivot table column?

Answer:  Select the column heading that you wish to remove subtotals on. In this example, we've chosen the column heading called Discount.

Right-click and then select "Field Settings" from the popup menu.

Under subtotals, select the "None" option. Click on the OK button.

Now when you return to the spreadsheet, the subtotals for each Discount are no longer visible.
