Wrong calculation with 2nd "% difference from" in Pivot Table

[antoine1]

Hello guys,
I have a simple table with 4 columns:
<b></b><table cellpadding="2.5px" rules="all" style=";background-color: #FFFFFF;border: 1px solid;border-collapse: collapse; border-color: #A6AAB6"><colgroup><col width="25px" style="background-color: #E0E0F0" /><col /><col /><col /><col /></colgroup><thead><tr style=" background-color: #E0E0F0;text-align: center;color: #161120"><th></th><th>A</th><th>B</th><th>C</th><th>D</th></tr></thead><tbody><tr ><td style="color: #161120;text-align: center;">1</td><td style=";">Date</td><td style=";">Product</td><td style=";">Qty</td><td style=";">Total</td></tr><tr ><td style="color: #161120;text-align: center;">2</td><td style="text-align: right;;">01/01/2010</td><td style=";">A</td><td style="text-align: right;;">5</td><td style="text-align: right;;">238,60</td></tr><tr ><td style="color: #161120;text-align: center;">3</td><td style="text-align: right;;">01/02/2010</td><td style=";">A</td><td style="text-align: right;;">5</td><td style="text-align: right;;">250,55</td></tr><tr ><td style="color: #161120;text-align: center;">4</td><td style="text-align: right;;">15/02/2010</td><td style=";">A</td><td style="text-align: right;;">3</td><td style="text-align: right;;">143,34</td></tr><tr ><td style="color: #161120;text-align: center;">5</td><td style="text-align: right;;">18/02/2010</td><td style=";">A</td><td style="text-align: right;;">12</td><td style="text-align: right;;">590,28</td></tr><tr ><td style="color: #161120;text-align: center;">6</td><td style="text-align: right;;">25/02/2010</td><td style=";">A</td><td style="text-align: right;;">13</td><td style="text-align: right;;">625,30</td></tr><tr ><td style="color: #161120;text-align: center;">7</td><td style="text-align: right;;">04/03/2010</td><td style=";">A</td><td style="text-align: right;;">17</td><td style="text-align: right;;">885,87</td></tr><tr ><td style="color: #161120;text-align: center;">24</td><td style="text-align: right;;">01/01/2011</td><td style=";">A</td><td style="text-align: right;;">20</td><td style="text-align: right;;">993,60</td></tr><tr ><td style="color: #161120;text-align: center;">25</td><td style="text-align: right;;">01/02/2011</td><td style=";">A</td><td style="text-align: right;;">21</td><td style="text-align: right;;">1030,47</td></tr><tr ><td style="color: #161120;text-align: center;">26</td><td style="text-align: right;;">15/02/2011</td><td style=";">A</td><td style="text-align: right;;">13</td><td style="text-align: right;;">679,25</td></tr><tr ><td style="color: #161120;text-align: center;">27</td><td style="text-align: right;;">18/02/2011</td><td style=";">A</td><td style="text-align: right;;">6</td><td style="text-align: right;;">308,94</td></tr><tr ><td style="color: #161120;text-align: center;">28</td><td style="text-align: right;;">25/02/2011</td><td style=";">A</td><td style="text-align: right;;">15</td><td style="text-align: right;;">800,40</td></tr></tbody></table><p style="width:2,4em;font-weight:bold;margin:0;padding:0.2em 0.6em 0.2em 0.5em;border: 1px solid #A6AAB6;border-top:none;text-align: center;background-color: #E0E0F0;color: #161120">Data</p><br /><br />

There is more data but I show only a part of it to keep this short.

I want my pivot table to display Qty and Amount, but also % difference from the same period in the previous year. So I repeat both columns in the pivot table and show them as "% difference from" and choose Year and 2010 in the dialog.

As you can see below, the Delta $ 2011 calculation gives the wrong answer: it actually displays the % difference between the 2011 Amount $17461.73 and the 2010 Qty 199...

I received no answers so I'm trying to simplify the data. I'm working on XP and Excel 2003, but I've tried this on W7 and 2007 with similar results. If I weren't so old I'd say this is an Excel problem, but I know better by now

My problem seems to be related to grouping dates, and then only when data is spread out horizontally.

If anybody is willing to take a look, please do the following.
1) Copy this data to a spreadsheet. Please note I use a d/m/yy setting, I'm not sure how this will come out, these dates should all be 1st day of Jan or Feb...
<b></b><table cellpadding="2.5px" rules="all" style=";background-color: #FFFFFF;border: 1px solid;border-collapse: collapse; border-color: #A6AAB6"><colgroup><col width="25px" style="background-color: #E0E0F0" /><col /><col /><col /><col /></colgroup><thead><tr style=" background-color: #E0E0F0;text-align: center;color: #161120"><th></th><th>A</th><th>B</th><th>C</th><th>D</th></tr></thead><tbody><tr ><td style="color: #161120;text-align: center;">1</td><td style=";">Date</td><td style=";">Product</td><td style=";">Qty</td><td style=";">Total</td></tr><tr ><td style="color: #161120;text-align: center;">2</td><td style="text-align: right;;">01/01/10</td><td style=";">A</td><td style="text-align: right;;">5</td><td style="text-align: right;;">238,60</td></tr><tr ><td style="color: #161120;text-align: center;">3</td><td style="text-align: right;;">01/02/10</td><td style=";">A</td><td style="text-align: right;;">12</td><td style="text-align: right;;">590,28</td></tr><tr ><td style="color: #161120;text-align: center;">4</td><td style="text-align: right;;">01/01/11</td><td style=";">A</td><td style="text-align: right;;">20</td><td style="text-align: right;;">993,60</td></tr><tr ><td style="color: #161120;text-align: center;">5</td><td style="text-align: right;;">01/02/11</td><td style=";">A</td><td style="text-align: right;;">6</td><td style="text-align: right;;">308,94</td></tr></tbody></table><p style="width:3em;font-weight:bold;margin:0;padding:0.2em 0.6em 0.2em 0.5em;border: 1px solid #A6AAB6;border-top:none;text-align: center;background-color: #E0E0F0;color: #161120">Hoja1</p><br /><br />
2) Build a Pivot Table with Date as columns, Product as rows, Qty and Amount as data cells. No General Totals for rows or columns.

3) Group Date by Years and Months. Then configure the new Years field to show automatic subtotals.

4) Add a second copy of fields Qty and Amount to the data section. As you do this, for both set the Options to show data as "% difference from" and use Years as base field and 2010 as base element.
Your table should look something like this, and the percentages displayed are correct:

5) Note the SUM of Total2 for TOTAL 2011 (lower right cell) is 57.14% which is the correct result of (1302.54 / 828.88) -1

6) Now drag the Data field cell under the columns headings. You should see something like this:

7) Take a look at SUM of Total2 for TOTAL 2011 (lower right cell). It now displays an incorrect value of 7562% which is exactly (1302.54 / 17) - 1. In other words Excel is taking the % difference between the 2011 Total and the 2010 Qty. This only seems to happen for the subtotal, the individual months are OK...

Can you see what is going on? Is there a workaround for this?

Thanks to all that take a look a this.
