Pivot table is useful to summary calculation for table. However, there isn’t a simple way to adjust multiple fields to the same function. The traditional way, you can right-click on the pivot table and adjust one-by-one.

Fortunately, there is the easy way to change multiple pivot-fields to the same function, by using the macro-excel. The full reference can be obtained from Moxie (2013). Here is a short macro that converts all the fields in a selected pivot table to the Sum function (code as xlSum) as follow:

Figure 1: Macro code for adjust multiple fields to the same function (reproduced from Moxie(2013)) (Note: Make sure you have selected the pivot table to change before playing the macro)

Public Sub PivotFieldsToSum()
' Cycles through all pivot data fields and sets to sum
' Created by Dr Moxie
Dim pf As PivotField
With Selection.PivotTable
.ManualUpdate = True
For Each pf In .DataFields
With pf
.Function = xlSum
.NumberFormat = "#,##0"
End With
Next pf
.ManualUpdate = False
End With
End Sub

You can change xlSum with other function such as: xlAverage, xlCount, xlCountNums, xlMax, xlMin, xlProduct, xlStDev, xlStDevP, xlSum, xlVar and xlVarP. The detail of each function is illustrated in Table 1.
