calculated field in Excel Pivot

Question

I am pretty sure that what I want to do is not possible, but I thought I'd give the experts a try.

I have a pivot table with countries in rows, date in columns and kgs, acreage and yield in rows. I am trying to make an estimation using calculated fields. What I want is (current)acreage*(previous date)yield. Kind of a modified "Show As" calculation. Any ideas?

Thanks in advance.

Answer 1

Assuming that columns AD are Date; Kgs; Acreage and Yield respectively and row 1 contains the labels, why not use a formula in column E.

As row 2 contains the first valid data, you would have to start at row 3. Therefore, cell E3 should contain the formula =C3*D2 which should be copied down to the last row of the pivot table.
