What is PowerPivot?
PowerPivot supports files up to 2GB in size. The 64-bit version of PowerPivot enables you to work with up to 4GB of data in memory, and the 32-bit version enables you to work with up to 2GB of data in memory (500 to 700MB files)
Excel 2010 (32-bit or 64-bit) is required to install PowerPivot for Excel.
Office Shared Features must be installed with Excel 2010. .NET Programmability Support, in Microsoft Excel, must also be installed.
PowerPivot for Excel is a free download that significantly expands the data analysis capabilities of Excel.

What can PowerPivot build?
Data Analysis Expressions (DAX)
Calculated Columns • Concatenate values • Create new values • Perform lookups
• Examples
• Month =CONCATENATE(FORMAT(MONTH([Datekey]),"00 "),LEFT([CalendarMonthLabel],3))
• Profit =[SalesAmount]-[TotalCost]-[ReturnAmount] • ProductCategory =RELATED(DimProductCategory[ProductCategoryName]) • LifetimeSales =SUMX(RELATEDTABLE(FactSales), FactSales[SalesAmount])
Data Analysis Expressions (DAX)
YTDSales = TOTALYTD(SUM(FactSales[SalesAmount]),DimDate[Datekey])
SalesAmount = SUM('FactSales'[SalesAmount])
CumulativeSales = CALCULATE(SUM(FactSales[SalesAmount]), DATESBETWEEN(DimDate[Datekey], FIRSTDATE(ALL(DimDate[Datekey])), LASTDATE(DimDate[Datekey])))

Measures
PY YTD Sales = TOTALYTD(SUM(FactSales[SalesAmount]), DATEADD(DimDate[Datekey],-12,MONTH))
Profit % = Sum([Profit])/Sum([SalesAmount])
Data Analysis Expressions (DAX)
