Calculated Field

You can add custom calculated fields into the value field area of a pivot table which calculates values using formulas. You can use constants or refer to other fields of the pivot table in the formula.

PivotTables offers the ability to calculate a measure field by formula Also support remove calculated field. You can get all calculated fields that set to the specified pivot table. Also support remove calculated field. The returned result has two properties: fieldName: the calculated field name. formula: the formula of the calculated field name.
