Maybe we ought to use one of the rounding functions with the result for Chai
SUM() Although we are using SUM() in a calculated column, it s a very common function to use in a measure as well SUM() is officially a Math & Trig function; that s why it s included here However, it has a lot in common with the Statistical functions, which is why it was also covered in the earlier chapter on aggregate (that is, Statistical with SUM() and SUMX()) functions The example uses the Products table Syntax
=SUM(Products[UnitsInStock]) Prac tical PowerPivot & DAX Formulas for Excel 2010
Result
Analysis
The formula returns the total number of all products in stock This may or may not be a valid aggregation; that s a business decision The result could be divided into UnitsInStock for each product to calculate the percentage contribution to total stock SUMX() Like SUM(), SUMX() is also a Math & Trig function It too was covered earlier when we looked at aggregate functions SUMX() is one of the Xfunctions, which means it requires a table (and not a numeric value) as its first parameter The example uses the Categories table C h a p t e r 1 1 : M a t h & Tr i g Fu n c t i o n s
Syntax
=SUMX(RELATEDTABLE(Products),Products[UnitsInStock]) Result
Analysis
Here RELATEDTABLE() is being used to return a table as the first parameter for SUMX() The second parameter is a numeric column in the referenced table The result indicates that, for example, we have 559 beverage products in stock If you add the figures for each row, the answer is 3119, the result of our total stock from the previous query TRUNC() This is our final Math & Trig function TRUNC() strips away decimals to leave a whole number The example uses the Products table Syntax
=TRUNC(Products[UnitPrice]) Prac tical PowerPivot & DAX Formulas for Excel 2010
Result
Analysis
You can return the same result by using INT() However, to illustrate the difference between INT() and TRUNC(), you may want to try the following two examples: =INT(72) =TRUNC(72) INT() and TRUNC() are the same when applied to positive values they behave differently on negative values The results are 8 and 7, respectively Part III

A Few Ideas: PowerPivot and DAX Solutions
Prac tical PowerPivot & DAX Formulas for Excel 2010
he real world is the real world Software, and books about software, can only give you outofthebox solutions Realworld solutions require a bit more work This chapter presents a few ideas for moving beyond outofthebox answers It is all about implementing PowerPivot and DAX to deal with common business problems The three appendixes that follow this chapter have a narrower focus, of how to write SQL, MDX, and DMX queries for assembling data in your PowerPivot model In contrast, this chapter is more concerned with using DAX and the PowerPivot GUI to provide solutions, once you already have the data in place That said, there is a little on importing data to address the problem of working effectively with dates and dealing with selfjoins Working with dates can lead to a number of problems some of these are addressed here There are also a few classic BI solutions in this chapter: percentage of total and subtotal, running totals, changes over time, moving averages, suppressing totals for nonadditive numbers, dealing with semiadditive numbers, customizing DAX formulas for individual rows or columns, predefining filters, predefining Column Labels and Row Labels with named sets, working without pivot tables, sharing your pivot reports with others through SharePoint, and a few other things Key concepts Date and time solutions, totals and subtotals, contributions to totals and subtotals, changes over time, nonadditive and semiadditive numbers, moving averages, prede ning lters and sets, selfjoins, working without pivot tables, PowerPivot for SharePoint Preparation Many of the examples in this chapter use a Northwind PowerPivot model Instructions on how to create this model from a SQL Server Northwind source are in 1 Instructions on how to do so from an Access, Excel, or data feed Northwind are in 2 One or two examples will use another data source, namely the SQL Server sample database, ContosoRetailDW
