How to use a Pivot Table to sum the last 12 columns

[victorsales]

Hi Everyone,

hope you can help....as usual.

I have a pivot table based on an enormous database which essentially summarises each month points by individual.

I need to keep all historical columns in the pivot (this is going back to 2012) but would like the pivot to calculate automatically the sum of the last 12 columns as soon as new data is added to it.

I need the field to be inside the pivot because we need to sort from lowest to highest points. Adding a sum outside the pivot works but doesn't allow me to sort any value.

Any way I can accomplish this?
Many thanks for your help.

Hi

The example below sums the last two columns:

Excel Workbook
	A	B	C	D
3		Values
4	Row Labels	Units	Total	Sum of Camp1
5	Andrews	592	5.474,19	6066,19
6	Binder	158	788,42	946,42
7	Desk	11	3.025,00	3036
8	Pen	56	111,44	167,44
9	Pen Set	226	1.127,74	1353,74
10	Pencil	141	421,59	562,59

Dim pf As PivotField, pfNew As PivotField, v, i%, c%, fs$
Application.EnableEvents = False
v = Split(Target.ColumnRange.Address, ":")
c = Range(v(1)).Column
fs = "="
For i = c - 1 To c - 2 Step -1                      ' build formula
    fs = fs & Cells(Range(v(1)).Row, i) & "+"
Next
fs = Left(fs, Len(fs) - 1)                          ' final formula
For Each pf In Target.CalculatedFields
    If pf.SourceName Like "*Camp*" Then             ' already exists
        pf.Delete
        Set pfNew = Target.CalculatedFields.Add("Camp1", fs)
    End If
Next
Target.AddDataField Target.PivotFields("Camp1"), "Sum of Camp1", xlSum
Application.EnableEvents = True
End Sub
