I am trying to reverse engineer an excel workbook pivot table. It's
weird. I can see the Pivot table and trying to find out how it was
done. I have done alot of internet searching for 2-3 days. I can see
the Source is going to a "Summary Sheet" but there is not one listed
on the tabs. I tried to find hidden sheets.. NONE.

Is it possible to have a Summary Sheet in Excel not listed as a normal
sheet?
How do I view it?

Thanks for your help in advance..
