My boss made a P&L (profit and loss) excel spreadsheet for FY13 and she wants me to simplify it for FY14 with various different drop down menus added. Now before I get into that, I still need to understand the big picture. The Excel sheet has two "master" sheets titled "Pivot_Master" and "Pivot_FuncDetail". I assume that the information is gathered from those sheets but why is there two?

In addition, there are about 10 different separate slides with headcounts and expenses (operating expensive and cost of goods sold). They all have different expense reports for the different sectors of the business.

I understand the basics of Excel. I understand how Power Pivot and Macros work, along with the formulas. However, I am having a hard time seeing where the data is pulled from. For example, in one of the expense sheets under headcount, this is the formula used for the Research and Development cell:

=IFERROR(GETPIVOTDATA(+$H$9,INDIRECT($H$11),"Fiscal Month",$E$6,"Line Item",$D14,"Profit Center SEC Func Area2", $C14), 0)

Now can someone explain this to me. Where is the Excel sheet pulling the data from? Is it Pivot_Master or Pivot_FuncDetail? Both Pivot sheets go down to about 700 rows with numbers and data and I am having a hard time seeing where they are pulling the information from.

Thank you for your help!
