Remarks

Use the Add method to add a calculated field to the PivotTable report. The default name (Field1, Field2, …) is assigned to the new field. Use the PivotField.Name property to rename the field.

A formula for the calculated field should conform to the common syntax rules and contain only supported elements:

In the formula, you can use constants and refer to other fields in the PivotTable report. Calculations are performed on the sum of the underlying data for any field in the formula. When you reference a field in your formula, you can enclose the field name in apostrophes or omit them.
You cannot create formulas that use a cell reference, defined name, circular references, or arrays.
You cannot use worksheet functions that require cell references or defined names as arguments.
The formula cannot refer to the PivotTable’s subtotals, totals, and Grand Total value.
The formula should use culture-dependent separators. Use the DocumentOptions.Culture property to specify the workbook culture.

After the calculated field is created, call the PivotTable.DataFields.Add method to add the field to the PivotTable’s data area.
