I hope you want to move the Period in the top of the Pivot table. First you need to add the Period in the Dimension and after creating the Pivot table you select the Period column and drag into above the Amount column. When you drag the column you will see a Arrow point which will indicate where the new position for the Period.
Attached the sample file for your reference. Hope this will resolve your problem.

I looked at your sample file, and it's exactly how I set mine up. However, in your pivot table, if I go to the Presentation tab and on the Period dimension select Show Partial Sums, I get a total column to the right which sums up the all the period totals for each row. That's exactly what I want to happen, except when I do the same thing on mine, nothing happens - I get no total column at all.
Any idea why I don't get the same results as you?
