Calculated element in a Pivot Table

Apr 29, 2016 at 3:11 PM
Hello. I created a pivot table with Epplus, but I need to insert a calculated element of one field of this Pivottable.
Can you tell me how to do it?

pivotTable.RowFields.Add(pivotTable.Fields("SITUACIÓN EOP"))

I need add a calculated element (not field) from the pivotTable.Fields("SITUACIÓN EOP").
