Calculated Items

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

PivotTables offers the ability to calculate a field item by formula It also supports removing calculated items. You can modify a calculated item by modifying the formula or priority of a calculated item. You can get information about all the Calculated items on this field by a Source Field Name. If you don't want to provide the name, then you will get all the information of the calculated item of the field You can decide whether the calculated values should be merged into the subtotal and grandTotal of the PivotTable. This is an option for PivotTable with the following data types: The GC.Spread.Pivot.CalcItemAggregation type is defined as follows:
